The best sun shirts act like wearable shade, protecting your skin while staying cool and breathable.
To assemble our most recent rankings, GearJunkie Editor Chris Kassar and lead tester Ryan Kempfer put two new sun shirts through a three-month cycle. From biking Utah’s red-rock arches to hiking the mosquito-thick tundra of Katmai, Alaska, we logged more than 30 days and 200 miles to find the layers worth living in all summer.
Our top overall pick, the technical Black Diamond Alpenglow Pro Hoody, won for its rare blend of protection, mobility, and versatility. For value, the Patagonia Capilene Cool Daily Hoody earned our budget award, pairing reliable comfort and coverage with a price we love. Over the past decade, our seven-person test team has vetted more than 50 sun shirts.
Editor’s Note: We updated our Sun Shirts guide on June 14, 2026, adding two sun shirts: the Marmot AirExchange UPF 50 Hoody for breathable, high-coverage performance and The North Face Sunriser Hoodie for lightweight comfort on hot, high-output days. We also reworked every review to improve scannability.
The Best Sun Shirts of 2026
Specifications
Pros & Cons
Pros
- Super-stretchy fabric
- Longer cut stays tucked under a harness or pack
- Breathable and quick-drying
- Well-designed features: thumb loops, zippered chest pocket, hood
Cons
- Pricey
- Not as soft as some others
- Durability questions
Versatile, technical, and — let’s be honest — just plain badass to wear, the Black Diamond Alpenglow Pro Hoody ($149) earned a spot as one of the most capable sun shirts in our test.
The Tech: A streamlined fit and stretchy fabric set the tone, backed by well-considered details. The helmet-compatible hood delivers broad coverage without fuss, and a zippered chest pocket adds storage you’ll quickly come to rely on. UPF 40 shields your skin from brutal exposure, while well-designed thumb loops hold steady without bunching.
What We Like: We put it to work everywhere from kayaking in Baja California to scrambling ridgelines in Wales, and it kept up at every turn. The breathable fabric sheds heat well, even in the midday desert sun, and the mobility shines during hard, sustained efforts. The longer cut tucks neatly under a harness or hip belt, which makes it a favorite among our climbers and backpackers.
What We Don’t: The fabric isn’t the softest against bare skin — nowhere near as plush as the NRS Silkweight — and it turns a touch clingy when you’re sweaty. Durability has limits, too. After several months of wear, we noticed light pilling and a few minor snags. At $149, it’s also one of the pricier shirts on the market.
Should You Buy It? If you log serious days outside and want a shirt that refuses to tap out, this is money well spent. Whether you’re chasing summits, threading slot canyons, or pushing through a hard trail run, the Alpenglow Pro backs up its price with smart design and a fit that makes you feel ready for anything.
Specifications
Pros & Cons
Pros
- Odor control keeps funky smell at bay
- Generous hood fits well with or without helmet
- Internal sewn loop for hanging shirt comes in handy
- Lightweight
- Great overall fit
Cons
- A little warm for really hot days
- UPF rating isn’t listed
For a no-frills sun hoody with recycled materials and legit odor-fighting power, the Patagonia Capilene Cool Daily Hoody ($70) is well worth a look.
The Tech: Patagonia builds it from recycled fabric and treats it with HeiQ Mint for odor control. The hood is generous but well-shaped, sitting comfortably with or without a helmet. Small touches like the internal hang loop round out an otherwise pared-down package.
What We Like: We ran it hard for months, from late-winter ski tours in Colorado to long, sweaty days under the Baja sun, plus trail running, kayaking, and surf fishing. To stress-test the odor control, we took an aggressive approach: sweat through backcountry ski laps, toss it in the dirty laundry, forget it for days, then repeat. It still smelled surprisingly fresh — better than most shirts we abused the same way.
What We Don’t: Our one real knock is the uncertainty around the UPF rating. Patagonia doesn’t list it clearly, and a 2021 UPF recall article suggests a range of 17-45, which is a wide gap for a sun shirt. On the hottest Baja days, we also reached for an airier layer like the Marmot AirExchange, since the Cool Daily runs slightly warmer in extreme heat.
Should You Buy It? Run hot and want to dodge the funk without spending big? The Cool Daily Hoody is one of the best values in the lineup, and for everyday sun coverage that shrugs off sweat and stink, it earns its keep.
Specifications
Pros & Cons
Pros
- Very lightweight fabric
- Arm gussets allow for plentiful mobility
- Top-notch hood
Cons
- Stitches show minor wear after a few uses
The Mountain Hardwear Crater Lake ($80) is the rare sun shirt you stop noticing the second you pull it on — soft, quiet, and cut to move with you mile after mile.
The Tech: Armpit gussets and a hint of stretch deliver real freedom of movement, while the athletic-but-forgiving fit stays close without turning clingy. Both versions add thumb loops, and the women’s cut includes a ponytail-friendly hood opening. At 5.5 ounces in a men’s medium, it’s also among the lightest we tested — but it’s the next-to-skin feel and fit that earn it this award.
What We Like: The fabric stays soft and smooth against the skin even when you’ve sweated through it — no clammy cling, no chafe under a pack strap. It breathes well enough that it rarely feels swampy on hot climbs and dries quickly once you stop. And the full UPF 50+ rating means all that comfort costs you nothing in sun protection — it matches the heavier REI Co-op Sahara Shade while feeling lighter on.
What We Don’t: The athletic cut won’t suit everyone — if you want a roomier, more relaxed drape, look elsewhere. It’s a stripped-down design too, with no chest pocket or storage to speak of. Sizing is true, so stick with your normal shirt size.
Should You Buy It? If your priority is a shirt you can wear sunup to sundown without thinking about it, the Crater Lake is hard to beat. It’s soft, it moves with you, and it breathes — comfort that holds up whether you’re climbing, running, or just out all day in the sun.
Specifications
Pros & Cons
Pros
- Exceptionally breathable and fast-drying
- Soft, barely-there feel
- True four-season versatility
- Packs down tiny
Cons
- Lower UPF rating than many competing sun shirts
If there’s a sun shirt that feels closer to wearing nothing at all, we haven’t found it yet. The Outdoor Research Echo Hoodie ($85) is the airiest layer we’ve tested, with just enough coverage to take the edge off the sun without weighing you down.
The Tech: At just over 5 ounces, the buttery-soft fabric breathes exceptionally well and moves moisture fast. Smooth seams sit flat under backpack straps, and the uniquely angled thumbholes secure the sleeves without digging into your hands. The cut is dialed too: mobile without being baggy, so air keeps moving as temperatures climb.
What We Like: We ran it through a full year of hard use, from standup paddleboarding on the Snake River to spring ski tours in the Tetons and bear-viewing in Alaska. Through all of it, the Echo breathed better than anything else we tested. It wicked sweat fast and held odor at bay across back-to-back travel and multiday backpacking trips. The fabric looks flimsy, but our sample showed no meaningful wear after a year.
What We Don’t: The one real knock is sun protection. The Echo carries just a UPF 15-20 rating, far below the UPF 40 of the Black Diamond Alpenglow Pro and the UPF 50 shirts in this guide. That’s the only thing keeping it from a higher all-around score. The trade-off is deliberate, though — it swaps maximum protection for breathability you’ll actually want to keep on when the heat cranks up.
Should You Buy It? Few shirts reward fast, sweaty days like this one. It packs down to almost nothing and breathes like open air, so runners, paddlers, and hot-weather hikers who care more about staying cool than maxing out UV defense will love it. Layer sunscreen underneath, and the Echo becomes the shirt you reach for first.
Specifications
Pros & Cons
Pros
- True UPF 50 protection
- Mesh weave breathes like little else at this rating
- Sheds heat fast on steep, sweaty climbs
- Flat-felled seams sit chafe-free under a loaded pack
Cons
- Heavier than ultralight picks
- Slightly boxy fit
Most sun shirts force a choice between maximum UV protection and maximum breathability. The Marmot AirExchange UPF 50 Hoody ($77) refuses to pick a side, pairing a bombproof UPF 50 rating with a fabric porous enough to breathe like mesh.
The Tech: The secret is Marmot’s AirExchange construction, a 100% polyester weave engineered to let up to 50% more air through than a standard tightly woven sun layer. At 6.1 ounces, it isn’t the lightest shirt here, but flat-felled seams keep it from chafing under a loaded pack. The athletic, true-to-size fit pairs with a three-piece hood that stays secure without restricting, and a hidden zip pocket stashes a key or card. An anti-odor treatment helps stretch the time between washes.
What We Like: We tested it during late-summer ascents in the high alpine and on exposed desert canyon hikes, and it consistently dumped heat faster than almost any other UPF 50 shirt we ran. Even working up a sweat on a steep approach, the faintest breeze cut straight through the fabric for instant cooling. Where the similarly rated Cotopaxi Sombra leans on thicker fabric to hit UPF 50, the AirExchange gets there with airy mesh. You feel the difference the moment the temperature climbs.
What We Don’t: That mesh-like build is also the catch. The fabric snags more easily on sharp branches than a heavier nylon blend, so we’d take care when bushwhacking. It also gives up a little ground to the featherweight options when every gram counts.
Should You Buy It? The AirExchange is the rare shirt that satisfies both camps. It delivers true UPF 50 defense without the stuffy, overheated feel that usually comes with it, so hikers, climbers, and backpackers who run hot but won’t compromise on coverage finally have a layer that works.
Specifications
Pros & Cons
Pros
- Built-in, chemical-free mosquito resistance
- Breathable and moisture-wicking in mixed conditions
- Adjustable hem seals out wind and bugs
Cons
- Boxy, oversized fit
- Lacks thumbholes for extra hand coverage
Built for coverage and bug season, the Royal Robbins Salathe Sun Hoodie ($110) is a more functional take on the standard sun shirt.
The Tech: Alongside solid UPF 40+ protection, it adds built-in mosquito defense through Royal Robbins’ MPT fabric, a tightly woven material engineered as a physical, chemical-free barrier against bugs. An adjustable hem helps seal out sudden breezes or relentless swarms. It skips technical touches like thumbholes, keeping the focus squarely on coverage.
What We Like: We tested it at the height of mosquito season in Alaska, exploring Lake Clark National Park and watching bears. It proved its worth fast: while plenty of people around us were getting eaten alive, we stayed relatively unscathed. The light, quick-drying fabric wicks sweat and takes the edge off the wind better than expected. Across changing conditions, it stayed breathable and comfortable, never clammy when the breeze kicked up.
What We Don’t: The roomy, boxy silhouette is the main catch. Because it runs so large, you’ll want to size down for a standard, trimmer fit. Next to a tailored, race-ready piece like the North Face Sunriser, the Salathe feels loose and far less suited to fast mountain missions.
Should You Buy It? Pack this for buggy, mixed-weather trips where mosquitoes are the real threat. It trades a little alpine precision for serious bug protection and easygoing comfort, making the Salathe a smart choice for anglers, paddlers, and backcountry travelers heading into the swarm.
Other Shirts for Fun in the Sun
Specifications
Pros & Cons
Pros
- Featherlight
- Fits like a second skin
- FlashDry wicks sweat fast
- Tailored cut won't flap or snag on the move
Cons
- Too technical-looking for casual wear
- Limited versatility
When your objective demands moving fast and light, extra fabric and a baggy fit only get in the way. The North Face Sunriser Hoodie ($80) answers with a tailored, athletic cut that won’t flap in the wind or snag on passing brush.
The Tech: At just 4.8 ounces, the Sunriser feels like a second skin. It’s made from 100% recycled polyester and treated with The North Face’s FlashDry technology, which pulls moisture to the surface for quick evaporation. Rather than thumbholes cut into the sleeve, it uses low-profile elastic thumb loops, and an anti-odor treatment keeps it fresh on repeat outings.
What We Like: During humid, high-output trail runs, this hoodie managed sweat better than nearly anything we tested. That fast-wicking fabric kept us from getting chilled during shady breaks and windy ridge walks. We’re also fans of the elastic thumb loops. They anchor the sleeves over the backs of your hands while running, yet never feel bulky when you’re not using them.
What We Don’t: That race-tuned focus narrows its range. The Sunriser looks and feels like a technical running piece, so it sacrifices the casual versatility of a more relaxed layer like the Free Fly Bamboo. UPF 40+ is solid, but it stops short of the UPF 50 heavy hitters for relentless, all-day exposure.
Should You Buy It? Built around pace and mileage, the Sunriser is tough to beat for fast-and-light days. It disappears against the skin and moves sweat as well as any shirt here, which makes it a natural pick for runners and fast packers who measure their outings in miles, not hours.
Specifications
Pros & Cons
Pros
- Great value
- Comfortable
- Lightweight
- Delivers full sun coverage
- Unique drawstring hood
Cons
- No pockets
- Slightly warm for super-hot conditions
- Durability concerns
A lot of shirt for the money, the REI Co-op Sahara Shade Hoodie ($60) delivers protection and comfort that belie its price.
The Tech: It pairs UPF 50+ sun protection with soft stretch fabric and a versatile fit. The men’s medium we tested weighed 7.1 ounces on our home scale, a bit heavier than ultralight picks. An antimicrobial treatment helps cut funk during multi-day use, and the clever internal drawcord hood cinches down for extra coverage across your forehead and cheeks.
What We Like: It’s comfortable, breathable, and easy to wear all day across a wide range of activities. The thumb loops are well-placed and protect your hands without pulling or bunching at the wrist. That cinchable hood is the real draw — it seals coverage across your forehead and cheeks, right where the Cotopaxi Sombra’s fixed scuba hood leaves you exposed.
What We Don’t: That extra weight comes at a cost. During hard efforts in extreme heat, the fabric can feel warm. It also lacks a chest pocket, which limits storage next to pricier options. Some testers noticed early pilling and wear after repeated use and washes, so frequent rock climbers or bushwhackers may want a tougher choice.
Should You Buy It? At $60, the Sahara Shade holds its own against shirts costing far more. For budget-minded hikers, bikers, and anglers who want dependable everyday coverage, its blend of comfort and protection is hard to top.
Specifications
Pros & Cons
Pros
- Buttery soft fabric
- Comfortable laser-cut thumbholes protect hands
- Great overall fit
- Super stretchy fabric for added mobility
Cons
- Thumb loops feel awkward when they aren’t in use/are folded into the sleeve
Soft, stretchy, and equally at home on the river or the trail, the NRS Silkweight Hoodie ($90) brings whitewater-grade build quality to a versatile sun layer.
The Tech: NRS made its name on whitewater gear, and that durability shows here. The fabric is exceptionally soft and stretchy, and it sits comfortably in the middle of the price range for the performance it delivers. Laser-cut thumbholes add hand coverage, and the cut works as well at the beach as on a ridgeline.
What We Like: We tested it on sunny days in Colorado and California, then put it through the wringer over a spring in Baja, where sun, salt, and wind expose weaknesses fast. Even after repeated dips in the Sea of Cortez, the Silkweight stayed impossibly soft. Most shirts would feel crusty or reek after that abuse, but this one felt fresh out of the dryer. Only the Free Fly Bamboo felt softer in our hands, and it can’t match the Silkweight’s resistance to salt and sun.
What We Don’t: It’s a touch heavier than the airiest ultralight shirts here, so dedicated gram-counters may notice. The laser-cut thumbholes also turn fussy when you’re not using them, and they can get sweaty if you fold them up inside the sleeve.
Should You Buy It? When comfort tops your list, and the conditions turn harsh, the Silkweight delivers. It protects, breathes, and somehow stays soft even through salt, sun, and sweat, making it a clear winner for paddlers and hikers chasing all-day comfort.
Specifications
Pros & Cons
Pros
- Very soft and comfortable
- High-quality, durable material
- Stylish
- Naturally odor-resistant
Cons
- Only rated to UPF 20+
- Won't keep you warm if you get wet
Read Review: I Wore This Layer Every Day for 2 Months
While most sun shirts lean on polyester, the Free Fly Bamboo Lightweight Hoodie ($78) stands apart with a fabric that’s 70% viscose derived from bamboo.
The Tech: The material difference is immediate. It feels like silk blended with cashmere, easily the softest shirt in our test. The design stays simple: one small chest pocket, no drawstrings, just sun protection and comfort. Sleeves and hem both run plenty long for full coverage.
What We Like: That glorious texture is the whole appeal, and it delivers. Against the polyester crowd that dominates this list, the Free Fly feels in a class of its own on the skin. We wore it as an everyday layer for weeks, and its plush, handmade feel made it the one we reached for off the clock. The slim cut breathes better than expected once you dial in the fit.
What We Don’t: Sun protection is the weak spot. At just UPF 20+, it can’t shield you like a true UPF 50+ layer, such as the REI Co-op Sahara Shade, so it’s not the shirt for all-day high-alpine exposure. The hood also won’t always stay in place during active use. And if you’re between sizes, plan to size up, since the cut runs slim.
Should You Buy It? This one is a cozy everyday layer over a hardcore technical performer. For casual sun coverage that feels incredible on the skin, the Free Fly Bamboo is hard to set aside, even if it’s not the shirt for a high-alpine all-dayer.
Specifications
Pros & Cons
Pros
- Comfortable drop hem and loose fit
- Helmet-compatible hood
- Thumb loops keep sleeves in place
- Small screenprinted logos aren't distracting
Cons
- Not impervious to holes
- Smaller manufacturer stock can sometimes be limited
Synthetics may dominate sun apparel, but they always battle funk. The merino-based Ridge Merino Solstice Lightweight Pullover Hoodie ($90) sidesteps that problem with odor resistance built right into the fiber.
The Tech: The (m)Force fabric blends 87% merino with 13% nylon, close to the ideal ratio for adding strength to an otherwise delicate fiber. At 145 g/m², it carries a bit more heft than ultralight synthetics, which boosts durability. A longer drop tail, extended sleeves, and low-profile thumbholes round out a well-shaped cut, and the roomy hood promotes airflow on the move.
What We Like: We tested it in Iceland, wearing it nine days straight and stripping it off only for quick dips in geothermal pools. It put up a strong fight against trail odor, outlasting most synthetics we’ve worn on similar trips. The UPF 30+ rating had enough muscle for full UV days, which we appreciated in a country where shade is scarce. Where treated synthetics like the Patagonia Capilene rely on a finish that can fade, the Solstice fights funk at the fiber level.
What We Don’t: Merino simply isn’t as rugged as a through-and-through synthetic, so it won’t shrug off abrasion the way a polyester shirt will. The UPF 30+ rating, while solid, also trails the UPF 50+ heavyweights for relentless high-alpine sun.
Should You Buy It? Long stretches without laundry are exactly where the Solstice earns its keep. It stays fresh long after synthetics give up, making it a compelling, low-stink case for wool on backcountry trips where washing isn’t an option.
Specifications
Pros & Cons
Pros
- Comfortable on the skin
- Stretchy
- Durable
Cons
- Material doesn’t feel as modern, or sleek
Tougher and more protective than most, the Cotopaxi Sombra Sun Hoodie ($75) is a smart addition to any active person’s quiver.
The Tech: With 50+ UPF and thicker fabric than most sun hoodies, it’s built for the high desert or anywhere altitude ramps up exposure. The scuba hood stays put, thumb loops keep the sleeves from migrating, and a knit zippered hip pocket stashes bars or gels. A Polygiene anti-odor finish lets you wear it several times between washes.
What We Like: On a grueling bouldering expedition, the Sombra impressed us where flimsier shirts would have failed. We scuffed the sleeves while projecting a climb, but that’s par for the course, and we doubt many ultralight hoodies would have survived as well. The thumb loops let us move freely without the sleeves constricting, and after we broke a sweat on the approach, the fabric dried quickly while we set up pads. The loose fit even works over a T-shirt.
What We Don’t: That protection comes at the cost of airflow. Amplified by the knit panels, it doesn’t breathe like an airy piece such as the Outdoor Research Echo, and in peak heat, you’ll feel the extra material.
Should You Buy It?: On abrasive rock at altitude, this is the shirt we’d grab. It trades ultralight airiness for toughness and serious coverage, which makes the Sombra a strong call for climbers and high-desert adventurers who put their gear through hell.
Specifications
Pros & Cons
Pros
- Good value
- Effective rear vents
- Stylish
- Comfortable & lightweight
Cons
- Not the most breathable material (aside from the vents)
The Mountain Hardwear Canyon shirt ($75) is a long-running staple given a fresh update, and is a clean button-up built for warm summer days.
The Tech: It’s a simple 100% polyester button-up, and the latest version is the best yet. The base fabric isn’t the most breathable on its own, but a row of small mesh vents along the shoulders’ backs boosts airflow without sacrificing coverage. The cut is handsome and form-fitting, polished enough to pass for semi-professional off-trail.
What We Like: We loved the lightweight, breezy feel, and those shoulder vents earned their keep in the heat. They can’t match the all-over airflow of a true mesh shirt like the Marmot AirExchange, but they’re well-placed and effective, moving air right where you sweat most. The button-up styling makes it versatile enough for outdoor activities and the duller errands of daily life alike.
What We Don’t: The trim cut is the catch. It fits snugly through the chest, so we’d size up if maximizing airflow matters to you. And while the vents help, the core fabric still breathes less freely than mesh-heavy or ultralight competitors, so it can run warm during hard efforts in extreme heat.
Should You Buy It? Want a button-up that looks as sharp in town as on the trail? The Canyon obliges. It’s a quality, reasonably priced do-it-all for warm-weather days, and the updated version makes a solid everyday companion for casual outings and light adventures.
Specifications
Pros & Cons
Pros
- Exceptional sun coverage
- Great value
- Big variety of colors (14) and size options (S–3XL)
- Extra-durable
Cons
- Heavier/less breathable
- No antimicrobial treatment
Proof you don’t need to spend big for solid sun coverage, the Baleaf Sun Protection Hoodie ($30) delivers real performance at a fraction of the usual price.
The Tech: At just $30, it’s the budget champion of the group. The fabric is lightweight and quick-drying, and it comes in 14 color options, more than nearly any shirt in this guide. The fit is relaxed and easy to wear, though it skips premium touches like a chest pocket and odor-control treatment.
What We Like: We expected major compromises at this price, but after several months across Baja, Colorado, and Southern California, we came away pleasantly surprised. It held up through kayaking, snorkeling, hiking, and trail running without complaint. It even survived multiple shower washes on the road while still feeling cool on warm days. For occasional users or anyone outfitting a group for a trip, the value is hard to argue with.
What We Don’t: The savings show in the details. Without antimicrobial treatment, it needs more frequent washing to stay fresh, unlike pricier shirts such as the Patagonia Capilene with its built-in odor control. The sleeves also run a little short when you use the thumb loops.
Should You Buy It? Not everyone wants to drop big money on a sun shirt, and you don’t have to. For casual sun-seekers and budget-conscious travelers who need coverage without the splurge, the Baleaf is one of the best bargains we’ve tested.

How We Tested the Best Sun Shirts
Our Expert Testers
For this update, GearJunkie Editor Chris Kassar and lead tester Ryan Kempfer led testing. Based in Jackson, Wyoming, Kassar tests layers while hiking, paddling, skiing, climbing, and guiding wildlife trips in exposed mountain terrain. Kempfer is a Teton-based guide, ski tech, and longtime mountain athlete who regularly puts gear to work while hiking, biking, and backcountry skiing. Contributor Rob Simpson tested for previous iterations from Salida, Colorado, drawing on decades of backpacking and climbing experience across the western U.S. and Europe.
This guide also reflects input from a broader GearJunkie team that has tested sun shirts for years in the field.

Our Testing Grounds & Process
Over the past nine months, we added two new shirts and kept returning picks in rotation, logging more than 100 days and 400 miles. Kassar, Kempfer, and Simpson wore them hiking, climbing, fishing, biking, skiing, paddling, backpacking, and guiding from Yellowstone to Arches to Katmai, with additional testing on the Snake River and in Baja and Alaska. Conditions ranged from hot desert trails and reflective water to windy ridgelines, buggy bear-viewing days, spring snowfields, and long approaches under a pack.
We judged each shirt on breathability, sun protection, fit, comfort, dry time, odor resistance, hood performance, and coverage. We tested mobility under a pack, PFD, or harness. Every sun shirt sees at least five outings before inclusion, though many have months or years of use behind them.
This guide reflects five years of testing, during which seven testers have worn more than 50 sun shirts across deserts, alpine terrain, rivers, coastlines, and high-elevation trails. We continue testing after publication and update this guide seasonally as new models arrive, old ones change, and long-term durability becomes clearer.
Our Sun Shirt Rating System
We scored each sun shirt in four categories on a 1-10 scale.
- Comfort/Fit considers fabric feel, cut, stretch, and how easily it moves with you.
- Sun Protection measures coverage, UPF rating, and how well the shirt shields against direct rays.
- Breathability looks at how effectively it manages heat and moisture during activity.
- Versatility/Features reflects design extras and adaptability, including hood performance, pocket placement, style crossover, and how well the shirt transitions between activities and conditions.
Note: The overall score is our complete impression after extensive wear and testing, not an average of the category scores.

Buyer’s Guide: How to Choose the Best Sun Shirt
Every shirt on this list offers sun protection, but each has a unique set of features, pros, and cons. Sun shirts come in a variety of materials and styles. Some excel at certain activities, such as climbing or hunting, while others are designed to do it all.
The popularity of sunshirts has recently ballooned, and there are more options to choose from than ever before. To help inform your decision, this buyer’s guide includes every relevant topic under the sun. If you’ve found yourself here in search of shirts designed for specific activities, we’ve got guides to the best recommendations for fishing and even flannel shirts.
Types of Sun Shirts: Button-Up vs. Hooded Pullover
There are multiple kinds of sun shirts on the market, but the baggy button-up and hooded pullover are the most popular by far.
Hooded Pullover
Climbers, trail runners, and mountain bikers generally prefer hooded pullover sun shirts typically made from 70-80% polyester and 10-20% elastane or spandex.
Not all sun shirt hoods are created equal, but the best ones fit comfortably and won’t blow off in the wind. Hoods offer immense sun protection benefits. We like hoods that cover the neck, ears, and forehead. If your activity of choice requires a helmet, choose a hooded polyester sun shirt. Well-designed hoods stretch easily over climbing and cycling helmets and stay put during active use.
Other key features of many hooded pullover sun shirts are thumb loops (which are great for back-of-the-hand sun protection), and high-cut collars that protect the chest and neck. Some of our favorites on this list include the Black Diamond Alpenglow Pro and the REI Co-op Sahara Shade.
The downside of a hooded sun shirt is the same as any pullover — they’re a bit of a pain to put on and take off. Plus, while many hooded sun shirts are light and breathable, most of them do not come with vents. A few exceptions include breathable pullovers like the Black Diamond Alpenglow Pro and Marmot AirExchange UPF 50 Hoody.
Still, for the most part, sun shirts in this style are usually ventless. One final downside of hooded pullover sun shirts — they get stinky. Elastane and spandex, in particular, develop unpleasant odors more quickly than natural fibers like merino wool.
Pro tip: If you want a hooded sun shirt without the stink, buy something made from natural fibers and minimal elastane. Solid choices include the Free Fly Lightweight Hoodie, partly made from bamboo-derived fibers, and the Ridge Merino Solstice, made mostly from merino wool.

Baggy Button-Up
For activities like fishing, hunting, and bird watching, choose a baggy button-up sun shirt. Button-up sun shirts typically come with a collar instead of a hood, which means you’ll also need to wear a protective sun hat if you want to protect your face, neck, and ears. Some models of button-ups come with a hood, giving you the best of both worlds.
Unlike the active-wear appearance of hooded pullover sun shirts, button-ups have a more traditional look. Most button-up sun shirts look perfectly at home at the bar or a backyard barbecue. Plus, they’re easy to put on and take off.
Anglers, in particular, tend to prefer button-up sun shirts for a few reasons. First, button-ups often come with pockets — a handy place to keep bits of spare tackle such as lures and tip-its. Also, many button-up sun shirts have vented panels, which increase airflow and breathability in warm conditions.
Ijn this guide, the Mountain Hardwear Canyon are our favorite button-up sun shirts.

UPF Rating Explained
Ultraviolet Protection Factor, or UPF, is the rating system that gauges a fabric’s effectiveness at filtering ultraviolet A (UVA) and ultraviolet B (UVB) light. For example, a fabric rated to UPF 30 allows roughly 3% or 1/30th of available UV to pass through it.
UPF ratings always fall between 15 and 50+. Garments below UPF 15 do not meet sun protection standards. Any fabric that allows less than 2% of UV to pass through rates UPF 50+.
Multiple factors can affect a fabric’s UPF rating. Darker colors tend to filter out more UV than lighter colors. Thicker fabric usually offers more protection than thinner fabric. A tighter weave may have reduced UV transmission compared to a loose and porous weave.
Brands work to solve the complicated problem of creating a light, breathable, and highly protective sun shirt. The recommended products on this list possess a fine balance of breathability, comfort, and performance, with impressive UPF ratings.
Brands conduct UPF tests on their own products. Just last year, Patagonia issued a voluntary recall on a series of sun shirts that failed to live up to their advertised UPF rating after independent testing.
In any case, reputable brands make all of the sun shirts on our list. As a general rule, we recommend purchasing a sun shirt with a UPF rating of at least 30 — especially if you have a fair complexion or recreate at high elevations.

Materials
Polyester is the most common base material for sun shirts for various reasons. Polyester offers far more protection than bleached cotton, which has a natural UPF rating of around 5. Plus, it dries much faster.
In recent years, many brands have incorporated 10-20% elastane or spandex into their sun shirts’ polyester weave. Integrating stretchy material is great for airflow and mobility but has some downsides. First, elastane can lose its springy quality over time. A shirt with lots of elastane or spandex probably won’t retain its original shape and fit in the long term.
Also, synthetic fibers like elastane develop odors faster than natural fibers like cotton or wool. Sun shirts are known for their gnarly stench, which can develop after a single day of sweaty outdoor recreation. Anecdotally, we noticed that shirts with a high elastane count did, in fact, seem to smell pretty bad after a workout.
Our research and testing found that most hooded pullover sun shirts are made from 80-90% polyester and 10-20% elastane or spandex. The NRS Silkweight Hoodie is an exceptionally soft version of this combination, winning it our most comfortable award. Of course, there are some exceptions to this. The Free Fly Lightweight Hoodie is made from 70% bamboo viscose, and the Ridge Merino Solstice is made from merino wool.
Button-up collared sun shirts tend to be made without spandex or elastane, so they aren’t as stretchy.

Breathability
Designed to protect against sunshine, sun shirts naturally need to be comfortable in warm conditions. A fabric’s breathability is defined by its ability to let air pass through. Breathability decreases drying time and also helps to minimize odor.
On this list, the Mountain Hardwear Crater Lake is the perfect choice for those looking for a sun shirt for active use in warm weather. It is important to note that increased breathability can sometimes lead to a decreased UPF rating, like we see in the Outdoor Research Echo, which is extremely breathable and has a soft touch feel to its fabric. A looser weave that allows airflow will let more UV reach the sun underneath.
All of the sun shirts selected for this list are relatively breathable. Sun protection is essential even in cooler conditions, but naturally, a hot summer day calls for breathable clothing.

Odor Resistance
Sun shirts are known for being a bit stinky. There are a few reasons for this. First, sun shirts tend to be worn for active use in warm conditions. Strenuous activity plus heat equals sweat, and sweat leads to odor.
Secondly, sun shirts are usually made from synthetic materials like polyester and elastane. Synthetic fibers are made from petroleum products — polyester threads are essentially thin ropes of plastic. Unlike natural materials like cotton and wool, synthetics don’t absorb sweat.
Instead, the sweat combines with bacteria from your skin and becomes trapped in between the fibers. Elastane fibers in particular are highly effective at trapping bacteria. Over time, the bacteria builds up — and so does the odor.
If you’re looking for a sun shirt that won’t ever smell, your search may continue forever. Luckily, some sun shirts are more odor-resistant than others. If you want to minimize the stink, we recommend following these three tips:
- First, don’t buy a sun shirt with a high elastane/spandex count. Most sun shirts are made from 10-20% elastane/spandex.
- Second, look for a sun shirt made from natural fibers. Bamboo is an increasingly popular alternative to polyester that may be less prone to unwanted odor.
- Third, purchase a sun shirt that has an odor-resistant treatment.
On this list, the Patagonia Capilene Cool Daily Hoody and the Black Diamond Alpenglow Pro are noticeably impressive in the odor-resistance category. They’re treated with Black Diamond’s HeiQ Pure Odor Control Treatment.

Hood
If maximum UV protection is your goal, you’re going to want a sun shirt with a well-fitted hood. The benefits of a hood are obvious: neck, face, and ear protection. However, not all hoods offer the same utility and value. For the most part, pullover sun shirts have hoods, and button-up sun shirts do not.
A hood that won’t stay on during active use is almost worse than no hood at all. During our testing, we wore sun shirts while hiking, climbing, and biking in windy conditions. The best hoods stayed on against the odds.
If your activity of choice requires a helmet, you’ll need a stretchy hood that can fit over it. One of our favorite hooded sun shirts is the Outdoor Research ActiveIce Hoody. The hood is well-fitted, helmet-compatible, and highly protective. We wore this sun shirt over a helmet for many months, and the material maintained its fit and elasticity.

Thumb Loops
The fingers and hands see a lot of sun exposure, making them susceptible to skin cancer. A sun shirt with well-placed thumb loops can help protect these vulnerable areas from excessive UV.
Most sun shirts with thumb loops are hooded pullovers like the NRS Silkweight Hoodie. In most cases, a thumb loop is a small opening that fits over the thumb and keeps the wrist and back of the hand covered by the sleeve.
Though most pullover sun shirts on this list come with thumb loops, surprisingly, a few styles do not. We love the thumb loops on the RE Co-op Sahara Shade. They’re positioned comfortably, and keep the entire hand’s back protected.

Fit
The way a sun shirt fits will define its performance. As a general rule of thumb, sun shirts should have a semi-loose fit. We particularly appreciate the fit of the Patagonia Capilene Cool Daily Hoody; it’s just right, not too loose and not too tight.
A loose-fitting sun shirt breathes better, and it’s less likely to limit your range of motion. However, if you usually wear a snug size medium at the office or out at the bar, we recommend sizing up to a large size when you purchase a sun shirt. One more reason to size up: for your sun shirt’s thumb loops to properly protect your hands, it needs to have full-length sleeves.

Price & Value
Budget
You can find a quality budget sun shirt for under $80. Many of our award winners, including the REI Co-op Sahara Shade Hoodie, Mountain Hardwear Crater Lake Hoodie, and the Patagonia Capilene Cool Hoody, are reasonably priced. These are durable, comfortable, lightweight, and have one or two additional features that make them stand out.
Mid-Tier
Sun shirts in this category run from $80 to $100. These will often be a little higher-performing than those in the budget category and may include wicking abilities, odor-control treatments, or higher UPF ratings. For example, the Outdoor Research Echo ($85) is a technical performance piece that is extremely stretchy and moves with you. Our most comfortable pick, the NRS Silkweight Hoodie ($90), is so soft and performs well in a variety of conditions.

Premium
Sun shirts with added versatility, storage, and durability will cost over $100. The Royal Robbins Salathe ($110) protects you from bugs and the sun at the same time.
Others in this category are technical pieces with unique features like large mesh underarm side vents found in the Black Diamond AlpenGlow Pro ($149), a high-performing sun shirt that’s ideal for climbing and high-output activities.
Frequently Asked Questions
Sun shirts are designed to protect against ultraviolet light during outdoor recreation. All clothing blocks some UV, but sun shirts are specifically crafted for this purpose, and the best of them provide much more protection than a typical cotton T-shirt.
To filter out UV, sun shirts combine effective materials with intentional weave/knit patterns. Most sun shirts are primarily made from polyester, which is rated as a top option for UV protection.
All of the sun shirts on this list come with a UPF rating. UPF stands for Ultraviolet Protection Factor. The UPF scale runs from 0 to 50-plus. The UPF number indicates the percentage of UV rays that are allowed to pass through the material. For example, a shirt rated UPF 25 allows 1/25 (or 4%) of the sun’s radiation to reach your skin underneath.
If you’re seeking maximum sun protection, look for a sun shirt rated UPF 50+, which will allow just 2% of UV (or less) to pass through.
Sun shirts are meant to be worn in the sun, so they need to be breathable to be comfortable. A nonbreathable sun shirt will perform like a sweat-trapping garbage bag.
For sun shirt manufacturers, it is a challenge to maximize breathability and minimize UV infiltration. Still, through a combination of high-performance materials and intentional weave/knit patterns, it can be done. The Mountain Hardwear Crater Lake is one of the most breathable sun shirts on this list. We’ve worn the Crater Lake while climbing and running in temperatures up to 100 degrees, and it always remained airy and comfortable.
Clouds may filter out some UV, but it’s very difficult to know how much. Strangely, certain clouds can actually create higher UV levels than a clear and cloudless day. In other words, it’s important to protect yourself from the sun, even when there are clouds in the sky.
