The best swim shirts for men cover your torso and arms with a quick-drying stretch fabric that protects against sun, chafing and wind. Most carry a UPF 50+ label, which means the fabric blocks most ultraviolet rays. They are popular for swimming, paddle sports, fishing and beach days, so the right pick depends on sleeve length, fit and how you will use it.
What is the best swim shirt for men? Based on ratings and rating volume, the Kanu Surf short-sleeve swim shirt and the baleaf long-sleeve UPF 50+ rash guard are the strongest picks here, with the Roadbox and Amazon Essentials shirts close behind.
In short: choose long sleeves for maximum coverage, short sleeves for comfort in the heat, and a looser fit for general swimming or a compression fit for active water sports.
The American Academy of Dermatology recommends light, covering clothing and choosing items with a UPF number on the label, and sunscreen on skin not covered. A swim shirt does not protect your neck, face, hands or legs, so those areas still need protection. UPF ratings on listings are manufacturer claims, so check the label when it arrives.

| Care | Rinse after salt or chlorine exposure and air dry to protect the fabric. |
Buying and Care Tips for Swim Shirts

Who Should Buy Swim Shirts for Men (and Who Can Skip Them)
A swim shirt is simple gear, yet it suits some activities far better than others. So use this quick guide before you choose.
- Good fit: anyone who spends hours on the water, such as paddlers, anglers and lifeguards, because sun exposure adds up over a long day.
- Good fit: swimmers who burn easily or who do not want to reapply sunscreen to the back and shoulders.
- Good fit: surfers and paddleboarders, since a snug shirt cuts down on chafing from boards and gear.
- Good fit: hikers and beach walkers who want light sun cover that dries fast.
- Can skip: a short dip on an overcast day. However, remember that UV light still reaches you through cloud.
Swim shirts also work as a base layer. For example, many people wear a snug one under a life jacket so the straps do not rub.
Sizing and Fit Guide for Swim Shirts for Men
Fit changes how a swim shirt feels in and out of the water. Compression styles hug the body and stay put when you swim. Loose styles feel more like a regular tee, but they can ride up in the water. The table below sums up the main styles.
| Fit style | How it feels | Best for | Watch out for |
|---|---|---|---|
| Compression | Snug, like a second skin | Swimming, surfing and paddle sports | Tight shoulders if you size too small |
| Athletic or slim | Close to the body with some room | Mixed water and land use | Chest and sleeve measurements |
| Loose or relaxed | Like a regular tee | Beach days and casual wear | Fabric that floats up and shifts in the water |
Most brands publish a chest and length chart, so measure your chest at its fullest point with a soft tape and compare. If you fall between sizes, read the brand notes on whether it runs small, and check recent reviews on fit. Also look at the sleeve chart, because long-sleeve cuffs vary by brand.
Common Mistakes When Buying Swim Shirts for Men
Even the best swim shirts for men disappoint when they are chosen for the wrong reasons. Therefore, avoid these errors.
- Trusting the UPF number alone: the label is a listing claim, and a loose, short shirt covers less skin than a snug long-sleeve one.
- Ordering your usual tee size: rash guards often run snug, so check the size chart first.
- Buying cotton: cotton holds water and feels heavy and cold, so look for quick-dry polyester or nylon blends.
- Forgetting uncovered skin: the face, neck, hands and legs still need sunscreen.
- Ignoring fabric thickness: thin, loosely woven fabric lets more UV through, and fabric usually protects less when it is stretched or wet.
Care and Wear Tips for Swim Shirts
A little care keeps the stretch and fit for many seasons. First, rinse the shirt in fresh water after every swim, because salt and chlorine can wear down elastic fibers. Next, wash it by hand or on a gentle cycle, and hang it to dry out of direct sun. Also skip fabric softener and high-heat dryers, since many care labels warn against both. Finally, read the care label on your exact shirt, because brands differ.
Wear the shirt the way you plan to use it. For example, a long-sleeve compression shirt works well under a life jacket, while a loose short-sleeve tee suits a walk along the shore. Replace any shirt whose fabric has gone thin or baggy, because it will protect less.
Low-Quality Swim Shirts Listings: Warning Signs
Many listings look alike, so check these points before you add a shirt to your cart.
- The UPF rating appears only in the title, with no fabric details to back it up.
- No size chart is shown, or the chart has no chest measurement.
- Recent reviews mention fading, split seams or sizing that is far off.
- The photos show a different style from the sleeve length or fit in the title.
- The fabric content is missing.
Frequently Asked Questions
What is the best swim shirt for men?
Based on ratings and rating volume, the Kanu Surf short-sleeve swim shirt and the baleaf long-sleeve UPF 50+ rash guard lead this list.
What does UPF 50+ mean?
It is a rating for how much ultraviolet radiation the fabric blocks. Higher numbers mean more protection.
Are rash guards the same as swim shirts?
The terms are often used interchangeably. Rash guards usually fit snugly; swim shirts may be looser.
Do swim shirts replace sunscreen?
No. The American Academy of Dermatology advises sunscreen on all skin not covered by clothing.
Should I choose long or short sleeves?
Long sleeves cover more skin; short sleeves are cooler. Choose by how much coverage you want.
How should a swim shirt fit?
Snug for water sports and loose for casual use. Check the size chart.
How do I wash a swim shirt?
Rinse after use and follow the label, usually a gentle wash and air dry.
Can I wear a swim shirt for hiking?
Many people do, especially the lightweight UPF 50+ shirts, though check ventilation and comfort.
Do swim shirts keep you warm in water?
They offer a little warmth but are not wetsuits.
Are the lower-rated picks worth buying?
All picks are rated 4.4 or higher with thousands of ratings, so fit and style matter more than rating.
How tight should the best swim shirts for men fit?
For swimming, choose a snug fit that does not restrict your shoulders, because loose fabric drags and rides up. For casual beach wear, a relaxed fit is fine. Check each brand size chart, since fit styles vary.
Can I wear a swim shirt in a chlorine pool?
Yes, swim shirts are made for pools and open water. However, rinse the shirt in fresh water afterward, since chlorine can break down stretch fibers over time.
Are long sleeves too hot in a swim shirt?
Wet, thin fabric usually feels cool in the water. On land, long sleeves can feel warmer in strong sun, so choose short sleeves or a loose fit if you run hot, and add a hat for the rest of your cover.
The Bottom Line
For most swimmers, the Kanu Surf short-sleeve swim shirt or the baleaf long-sleeve UPF 50+ rash guard is the safest buy here, and the Roadbox and Amazon Essentials shirts are strong alternatives.
Whatever you choose, check the size chart, rinse it after use and apply sunscreen to uncovered skin.
