A good trail-running cap is lightweight, wicks away sweat, and stays on your head without needing to be tightened. If you have to tighten it while running, it’s not the right cap for you. As for the rest, a stiff or soft brim and the color come down to personal taste and head shape.
We have several models for men. The Sunkar comes in the most designs, from the Breton flag to the Hénaff breton-striped shirt. The Exosun features our SAA, Society, and Snow Gold collections. The Heol Redek, available in black or white for €40, is UPF 50 certified: it offers the best sun protection. And the Akxon Cap comes in three colors. All are designed in Brittany using our own fabrics.
How to choose a trail-running cap
Lightweight and easy to pack
You should forget you’re wearing a trail-running cap. On a long run, a few extra grams eventually press on your forehead and make your head feel hot. It should also fold into a vest pocket when the sun goes down, without staying creased.
It wicks away sweat
This is what sets a sports cap apart from a city cap. The sweatband across your forehead should absorb sweat and then dry, not hold onto it. A cap that stays wet gets heavy, slips, and makes sweat run into your eyes, often at the worst time, in the middle of a technical descent. The top of the cap should also let air through.
It stays in place without being tight
A good cap stays in place because of its shape, not because you’ve tightened the closure all the way. If it’s too tight, it leaves a mark on your forehead and becomes painful after a few hours. To test it: adjust it without tightening, then shake your head from side to side. It shouldn’t move.
Stiff or soft brim
A stiff brim offers better protection from low sun and rain, but it gets misshapen if you squash it in a bag. A soft brim fits anywhere: handy if you often take your cap off and put it back on. On a long run in full sun, the stiff brim is easier on the eyes.
Protecting yourself from the sun
Not all fabrics block UV rays equally, and a thin cap may let some through. The UPF rating measures how much gets through: UPF 50 means that only one-fiftieth of UV rays pass through the fabric. That’s the case with our Heol Redek. To protect the back of your neck and ears too, which a cap doesn’t cover, choose a bucket hat instead.

Why so many designs
Many brands offer their trail running caps in three technical colors: black, gray, and blue. Yet we spend hours outdoors, often in groups, and like to have gear that reflects who we are.
That’s why our Sunkar comes in so many designs, from the Breton flag to the Breton-striped shirt, paisley, and leopard print. Technically, it’s the same cap: only the pattern changes, so choose the one you like. And we regularly add more.
Kinetik is a family-run Breton company. We design our products and fabrics ourselves instead of choosing them from a catalog, and our athletes test them before we approve them. We also outfit clubs, teams, and race organizers with gear in their colors.
Frequently asked questions
Cap or bucket hat for trail running?
The cap doesn’t obstruct your side vision and is easier to store, so it works anywhere, including on technical terrain. The bucket hat provides better protection for the back of your neck and ears from the sun, but slightly reduces your side vision. When it’s very hot and you’ll be out in the sun for a long time, the bucket hat is a better choice; the rest of the time, a cap is enough. See also our men’s bucket hats.
How can you keep your cap from blowing away or slipping?
A cap in the right size stays in place because of its shape, not because it’s tightened. If it moves, the size often doesn’t match your head circumference, rather than there being a problem with the adjustment. To check: adjust it without tightening and shake your head from side to side. If it moves, change sizes instead of tightening it further.
Stiff or soft brim?
A stiff brim offers better protection from low sun and rain, and keeps its shape. A soft brim folds into a vest pocket without creasing. If you take it off and put it back on often during your run, choose the soft brim. If you wear it from start to finish in a race in full sun, the stiff brim is more comfortable.
How do you measure your head circumference?
Place a flexible tape measure just above your eyebrows and ears, where your head is widest, without pulling it tight. This measurement determines your hat size, not your clothing size. Then check the size guide on the product page: head measurements vary from one model to another.
How do you wash a running cap?
Hand wash in lukewarm water, without fabric softener: it clogs the technical fibers, making the fabric less effective at wicking away sweat. Pay special attention to the forehead band, where salt builds up. Leave it to air-dry in its original shape, never in a tumble dryer or on a radiator, which can warp the brim.
Can a trail running cap also be used on the road?
Yes, no problem. On the road, it needs to do the same things: be lightweight, wick away sweat, and stay in place without squeezing. Trail running is simply more demanding, with more hours in the sun and rougher terrain. So a cap designed for trail running works everywhere.
What does UPF 50 mean on a cap?
The UPF rating indicates the amount of UV that the fabric lets through. UPF 50 means that only one-fiftieth gets through, so 98% is blocked. That’s the rating of our Heol Redek. During a long race in full sun or in the mountains, you won’t notice the difference at first, but your scalp and face will receive much less UV over the hours.
Can you customize a cap in a club’s colors?
Yes, we equip clubs, teams, and race organizers with gear in their colors. Minimum quantities, lead times, and how it works are explained on our dedicated pages for clubs and event organizers.
