Men's Sun Protection Shirts
Keep the sun off and the airflow up in KÜHL men's sun protection shirts.
Built for hot trail days, exposed ridgelines, and high-glare desert work, men's sun shirts pull double duty as your first line of defense against UV and your most-reached-for layer when the temperature climbs.
Choose from a variety of fabrics, styles, and features for the sun protection shirts that match how you move:
Lightweight Sun Coverage. Sun shirts in this collection deliver UPF protection ranging from UPF 30+ to UPF 50+, blocking the bulk of harmful UV without the weight of a traditional shirt. Quick-dry, moisture-wicking fabrics pull sweat off the skin so you stay cooler in direct sun.
Stretch Where You Need It. Built with 4-way stretch, these shirts move with you on scrambles, paddle strokes, and long miles under a pack. A lightly relaxed cut lets air circulate, while reinforced construction keeps the fit clean from shoulder to hem.
Short-Sleeve Performance. For peak summer heat, short-sleeve options pair mesh ventilation with odor-resistant finishes, easy to wear on the trail and tidy enough for town stops afterward. For cleaner button-up styling and broader summer-shirt options, see our men's short sleeve shirts collection.
Long-Sleeve Coverage. On exposed alpine, desert, and high-altitude days, a long-sleeve sun shirt blocks far more UV than sunscreen reapplied through a sweaty afternoon. Browse the broader men's long sleeve shirts lineup when sleeve length is the deciding factor.
Merino-Blend Options. When odor resistance and temperature regulation matter more than raw drying speed, merino-blend tops earn their keep. See our men's merino wool collection for the warmer-leaning end of the sun-shirt spectrum.
Look for signature touches like thumb loops to keep sleeves anchored over the back of your hands, articulated construction for unrestricted reach overhead, flatlock seams to prevent chafe under pack straps, and ripstop reinforcement at high-wear zones.

Sun protection shirts built for hot trail days, exposed ridgelines, and high-glare travel: UPF coverage, quick-dry comfort, and shirts that actually breathe.
What makes the best sun protection shirts for you?
The best ones check four boxes: UPF 30+ to UPF 50+ coverage, quick-dry moisture-wicking fabric, construction that moves with you, and a fit that wears all day without binding.
Beyond the spec sheet, the real test is how a shirt holds up across activities. A sun shirt that excels on a peak attempt should also be the one you reach for at a weekend barbecue. Look for 4-way stretch, flatlock seams, and a relaxed-but-not-baggy cut. That combination separates a true performance shirt from a tee with a UPF tag.

What fabric is best for performance shirts: synthetic, merino, or blend?
It depends on the trade-off you're willing to make.
Synthetic (polyester or a nylon-spandex blend) dries fastest, wears toughest under pack straps, and handles repeated washing without losing shape, the go-to for hot, sweaty day trips.
Merino wool earns its place on multi-day trips: it resists odor for days, regulates temperature across a wider range, and feels soft against the skin even when damp. The trade-off is slower drying and higher cost.
Merino-synthetic blends split the difference: most of merino's odor resistance and comfort with closer-to-synthetic durability and dry time.

Do you really need a technical shirt, or will a cotton tee do?
A technical shirt earns its place the moment you start sweating.
Cotton absorbs moisture and stays wet against your skin, uncomfortable in heat, dangerously cold once the wind picks up. A technical sun shirt does the opposite: moisture-wicking fabric pulls sweat to the outer face where it evaporates, quick-dry construction means you're not still damp at lunch, and UPF protection stays consistent whether the shirt is bone-dry or soaked.
For around-town wear in mild weather, cotton is fine. For anything where sun, sweat, or distance matters, leave the cotton tee at home.

Can you wear long-sleeve shirts in summer?
Yes, and on high-sun days, a long-sleeve UPF shirt protects far better than a short-sleeve plus sunscreen.
Counterintuitive as it sounds, the right long-sleeve sun shirt keeps you cooler than bare skin:
Counterintuitive as it sounds, the right long-sleeve sun shirt keeps you cooler than bare skin:
- Lightweight UPF 50+ fabric blocks the vast majority of UV across both arms without sunscreen reapplication.
- Mesh ventilation under the arms and a slightly relaxed fit keep air moving.
- Sleeves block bug bites, brush abrasion, and sunburn, all in one layer.
How should a sun protection shirt fit for layering?
A sun protection shirt should fit trim enough to layer cleanly under a vest or shell, with enough room across the shoulders and chest for unrestricted movement.
Articulated sleeves and a gusseted underarm matter more than the size on the tag. They're what prevent the shirt from riding up when you reach overhead. The shoulder seam should sit at the edge of your shoulder, not down on your bicep, so a pack strap doesn't ride on the seam.
When the sun shirt is functioning as a layer over a men's base layer top, size for the base layer underneath.

What's the best sun protection shirt for hot weather hikes?
For hot-weather hikes, look for an ultra-breathable shirt with UPF 50+, mesh ventilation, and a moisture-wicking fabric that dries fast between water crossings.
The construction details matter as much as the fabric. Flatlock seams prevent chafing under pack straps over long miles. A slightly relaxed cut allows airflow without flapping. Thumb loops anchor the sleeves on exposed sections so you don't lose UV coverage to sleeve creep.
Stay protected and on the move this summer.
