I'm a Former Raft Guide—These 8 Swim Shirts Changed the Way I Stay Cool on the Water
Table of Contents
May 2026 UpdateAfter testing during an epic Costa Rican adventure, we named thePatagonia Capilene Cool Sun Hoodie ($89)our best swimming shirt all-around. Meanwhile, theOutdoor Research Echo Hoodie ($85)impressed us with its odor-fighting abilities. We reviewed this article to ensure all products and prices were accurate, adding pros and cons and a comparison chart to help shoppers chose the right swim shirt for them.
Prepare for a bold statement: Embracing the polyester sun shirt while raft-guiding in 2002 was the single biggest “gear level-up” of my life. I found I had nearly double the energy at the end of the day simply by keeping the sun off my back and arms. Plus, jumping into the water created an instant, built-in swamp cooler.
Now, 24 years later, I always wear a long sleeve swim shirt for long days on the water orin the mountains. Protection from the energy-sucking—and often dangerous—sun is a gift that keeps giving. While most embrace swimming as a time to shed layers, the best swim shirt is actually a secret weapon for spring and summer water activities. After testing the swim shirts for men during an action-packed trip to Costa Rica, I’ve found the best options that move with your body, dry instantly, and (bonus) actually look good in photos. Swimming shirts might not be as life-changing for you as they were for me, but the right shirt will undeniably make your days under the sun more comfortable and less exhausting.

Best Swim Shirt All Around
Patagonia Capilene Cool Sun Hoodie
Sizes:S—XLSun Protection:UPF 40+
+ Versatile design looks like a casual hoodie+ Smart chest storage pocket+ Premium Capilene Cool fabric feels light, even if water– Zippered chest pocket may cause chafing
Patagonia’s Capilene Cool Sun Hoodie ended up being the most versatile swimming shirt in the entire test. It felt just as natural during long swims as it did wandering through town or lounging at the resort. The standout feature was the zippered chest pocket, which proved perfect for stashing my phone or a quick snack for my daughter when I was out of the water. While swimming or doing underwater pool workouts the pocket remained surprisingly unobtrusive, though during longer surf sessions it caused a bit of chafe after about an hour of paddling.
The long sleeve swim shirt uses Patagonia’s Capilene Cool fabric, a lightweight recycled polyester blend designed to wick moisture and dry quickly. In the water, it felt light and never heavy or clingy. Out of the water, it dried quickly in tropical heat. One thing I loved was the subtle textured exterior of the fabric, which helps the shirt drape naturally rather than sticking to your skin when wet. It looked more like a casual hoodie than a technical swim shirt, making it easy to wear all day. Capilene has long been one of Patagonia’s most versatile fabrics, and that showed here. Whether I was swimming laps, surfing, or sitting still during meditation, the shirt seemed to disappear on my body.
The button at the collar is also cleverly placed. Clip it closed and the hood provides full neck coverage for serious sun protection. Leave it open and the shirt looks more relaxed.
Best Odor Mitigation
Outdoor Research Echo Hoodie
Sizes:S—XXLSun Protection:UPF 15
+ Best odor control of all the swimming shirts we tested+ Lightweight and well-ventilated+ Ideal for travel, especially if laundry isn’t an option– No added warmth if temperature drops
The Echo Hoodie survived what might have been the most brutal test in this entire lineup. After several wet sessions, I packed all of the swim shirts into a plastic bag with plans to dry them later. Instead, life intervened and the bag sat sealed for 48 hours in tropical heat.
When I finally opened it, the smell was truly awful. Each swimming shirt got an immediate sniff test. Some failed spectacularly. The Echo Hoodie, somehow, did not stink. Credit the ultralight AirVent polyester fabric, which is designed to maximize airflow and moisture evaporation. That breathability appears to help prevent odor buildup as well.
The long-sleeve swim shirt is also one of the lightest swim shirts in this test, making it ideal for hot climates where airflow matters more than insulation. In the water it felt featherlight and dried extremely quickly afterward. The Echo would be my top swim shirt suggestion for someone traveling light or planning multi-day adventures where laundry isn’t an option.
Best Swim Shirt for Temperature Regulation
Kühl Eclipser Hoody
Sizes:S—XXXLSun Protection:UPF 50+
+ Infused with graphene to help regulate body temperature+ Strategic ventilation across the body+ Stretchy for dynamic movements– One of the more expensive swimming shirts we tested
The Kühl Eclipser Hoody felt like it was made from some magical elf-cloth straight out of Lord of the Rings. The magic ingredient is graphene, a material Kühl integrates into the fabric to help regulate body temperature and dissipate heat. In practice, that translated into one of the most interesting sensations in the entire test. Jumping from humid 85-degree tropical air into a cool swimming pool normally triggers a jolt of cold shock. But wearing the Eclipser softened that transition. The fabric seemed to disperse the coolness of the water evenly across the swim shirt, making the temperature change feel smoother and less abrupt.
The sun shirt also excelled during land-based workouts. Kühl uses strategically mapped knit zones that place lighter, more breathable fabric in high-heat areas while maintaining structure elsewhere. That meant the shirt moved incredibly well during yoga flows and mobility drills without ever feeling restrictive.
Despite the technical fabric, it remained lightweight and comfortable for swimming and beach runs. If you tend to bounce between high-output activities and water throughout the day, the Eclipser offers one of the most advanced temperature-management systems in any sun shirt I tested.
Best In the Water
Columbia Wild Cast Sun Hoodie
Sizes:S—XXLSun Protection:UPF 50
+ Strong thumb loops stay comfortably anchored in place+ Slim fit resists creating drag+ Quick-drying– Your loved ones may try to steal it
One of my favorite testing signals is when people start fighting over a piece of gear. That happened repeatedly with the Columbia Wild Cast Sun Hoodie. My wife actually apologized for stealing it halfway through the trip because it worked so well as both a swim layer and a sun shirt.
The Wild Cast uses Columbia’s Omni-Shade UPF 50 fabric, a lightweight polyester blend that provides super-thoroughsun protectionwhile staying breathable in hot conditions. While we stayed cool and sunburn-free on land, the real magic happened when we got it wet. Unlike some sun shirts that become baggy in the water, the Wild Cast maintained a streamlined feel that moved naturally while swimming or paddling. It never felt heavy or draggy, even during long pool workouts. The thumb loops were another standout feature. They kept the sleeves anchored over the backs of my hands and prevented the shirt from riding up my arms while swimming laps or pushing through underwater resistance workouts. Out of the water, the swim shirt fabric stayed impressively cool in the tropical heat and dried quickly between sessions.
Most Comfortable Swimming Shirt
HUK Airweight LS Hoodie
Sizes:S—XXXLSun Protection:UPF 40+
+ Soft and silky enough to sleep in+ Moved fluidly underwater+ Provided enough airflow for humid, stuffy conditions– Failed our stink test
Calling a swim shirt “airweight” is bold, but the HUK Airweight LS Hoodie lives up to the hype. The shirt uses a 90 percent polyester, 10 percent spandex blend that is exceptionally soft against the skin. On land, the fabric genuinely felt silky. I actually fell asleep wearing it one afternoon and immediately thought, this would make a greatpajama shirt.
In the water, the Airweight lived up to its name. The lightweight fabric moved fluidly during swim workouts and never felt restrictive or heavy. The sun shirt stretched naturally with every movement, even while lugging around 35-pound weights in the pool during underwater training sessions. It also breathed extremely well in humid environments, making it comfortable during beach workouts and walks through town between surf sessions.
The only downside appeared during our unofficial “stink stress test.” After repeated sweat sessions and time spent sitting wet in a gear bag, the Airweight developed odor faster than some of the other swimming shirts.That’s not unusual for lightweight synthetic fabrics, but it means you’ll want to dry this swim shirt out thoroughly between uses.
Best Swim Shirt for Surfing
Dakine Rincon Short Sleeve Raglan Rashguard
Sizes:M–LSun Protection:UPF 50+
+ Short-sleeved design aids mobility+ Seamless, chafe-free construction+ Stylish pattern was appropriate for in-town wear– Less coverage, since it’s short-sleeved and lacks a hood– Limited sizing
The Dakine Rincon Rashguard was the swim shirt I grabbed most often when I wentsurfing. The short-sleeve design and lack of hood mean it sacrifices a bit of sun protection compared to full sun hoodies, but that tradeoff paid off in mobility. The raglan sleeve construction eliminates seams across the shoulders, allowing for a full range of motion while paddling. That freedom made a noticeable difference during three-hour-plus surf sessions.
The fabric is a poly-spandex stretch blend, which hugs the body just enough to prevent excess drag while still remaining comfortable. Stylistically, the shirt also stands apart from traditional rashguards. The shibori-inspired wave pattern looks more like a casual surf tee than technical gear. I wore it exploring the towns of Quepos and Jacó without feeling like I had just walked off the beach.
The biggest surprise came during odor testing. After multiple sessions of being stuffed wet into a gear bag and worn repeatedly without washing, the Rincon remained remarkably stink-free. If you’re traveling with limited gear and need one surf-focused top that can handle repeated use, that kind of odor resistance is a huge bonus.
Best Swimming Shirt for Multi-Sport Athletes
The North Face Summit Direct Sun Hoodie
Sizes:S–XXLSun Protection:UPF 40+
+ Deep quarter-zip helps vent heat quickly+ Strong moisture-wicking abilities and dries rapidly+ Excellent mobility through upper body– Quarter-zip design isn’t a fit for surfing– Most expensive shirt we tested
The Summit Direct Sun Hoodie is the most technical piece in this lineup, and it shows. Designed as part of The North Face’s Summit Series, the swim shirt blends high-output performance fabric with sun protection, making it ideal for athletes who move constantly between land and water. The quarter-zip front isn’t ideal for surfing (zippers on chests and boards don’t get along), but it’s incredible for regulating body temperature during hikes, runs, or mobility workouts. When I felt the humidity stifling me during a workout, I would dump heat instantly by opening the zip.
The fabric itself is ultralight and highly breathable, designed to wick moisture quickly while providing UPF sun protection. Even after swimming, the shirt dried quickly enough to remain comfortable duringlong walksor beach workouts. The cut also provided excellent mobility through the shoulders and arms, making it ideal for climbing, hiking, and scrambling. What stood out most was its versatility. This is the one shirt in the test that I could easily see packing for a backpacking orhut tripthat includes alpine lake swims.
Best Flair
Party Shirt International Poppers Sun Hoodie
Sizes:XS–XXXLSun Protection:Not listed
+ Playful, fun-first print+ Surprisingly functional, given its style-first looks– Less technical than other shirts we tested– No UPF rating listed on website
It’s not hard to look a little too serious in a hooded sun shirt unless it’s this one. The Poppers Sun Hoodie from Party Shirt International brings an unapologetically fun aesthetic to a category dominated by muted fishing shirts and minimalist performance gear. This shirt earned more compliments than anything else in the test thanks to its loud, playful print.
Despite the casual vibe, it still performed surprisingly well during workouts and pool sessions. The lightweight poly-spandex fabric stretched easily during swim workouts and land-based exercises. It’s not as feature-rich as some of the more technical tops I tested, but the material dried quickly and remained comfortable even after repeated water exposure. The thumb loops helped keep the sleeves anchored and prevented the shirt from riding up during swimming and mobility drills.
Where the Poppers really shines is morale. It’s the swim shirt I will reach for when I want to remind myself that outdoor adventures are supposed to be fun, even if the output is of the type-2 variety. This will absolutely become my rafting andspring ski-touringsun shirt whenever I need a little extra shot of enthusiasm.

How I Tested Swim Shirts
Testing the best swim shirts properly means putting them in the environments they were actually designed for so I left my freezing hometown of Ashland, Oregon, and headed somewhere warm. I conducted the bulk of the testing in Jacó,Costa Rica, where the tropical heat, humidity, and constant access to the ocean created ideal conditions for evaluating swim shirts the way most people actually use them. For me, that looked like long days that moved fluidly between water and land.
The basecamp for the testing wasSurf Synergy Surf and Wellness Resort, which turned out to be a nearly perfect laboratory for swim shirt testing. The schedule there runs from sunup to sundown with a steady mix of activities, allowing me to put each shirt through a wide range of real-world scenarios. Over the course of the week I rotated through the shirts while surfing, swimming laps, doing breath training in the pool, cold plunging, and flowing through yoga and mobility sessions.
I logged more than 20 hours in the Pacific Ocean during the trip which helped reveal how the shirts handled paddling, repeated wipeouts, and extended time fully submerged. But the variety of other activities mattered too. Breath training and pool sessions helped highlight mobility and drag in the water, while cold plunge-to-sauna transitions offered a surprising look at how different fabrics handled rapid temperature swings.
Equally important were the quieter moments. I wore the shirts during meditation sessions, beach walks, and even while playing in the pool with my daughter. Those lower-intensity scenarios revealed things that high-output testing sometimes misses: how a fabric drapes when wet, whether a hood stays comfortable when sitting still, or how quickly a shirt dries in tropical heat.
Together, those repeated tests combined with long days of surfing and movement in Jacó’s humidity created a testing environment that closely mirrored how these shirts are actually used. Instead of evaluating them in isolation, I was able to sweat in them, swim in them, dry them in the sun, and then do it all again the next day, which provided a much clearer picture of how each shirt performs in the real world.
