Single-layer mesh traps heat like a sauna. TrekAir’s Dual-Layer Breathability System creates open corridors that flush hot air out and pull cool drafts in — keeping your head up to 15° cooler during activity.
THE CAP BUILT TO SOLVE THE ‘SWEAT DOME’ PROBLEM
KEEPS YOUR HEAD 15° COOLER
STOPS SWEAT STAINS BEFORE THEY START
Normal caps soak sweat, stain fast, and sag after washing. TrekAir’s airflow channels let moisture evaporate before it sets in. Reinforced stitching and machine-washable design keep it fresh and sharp.
MAINTAINS FOCUS UNDER PRESSURE
Even small rises in head temperature drain stamina and wreck focus. TrekAir’s dual-layer ventilation clears heat while its ultralight, precision fit disappears on your head — no slipping, no headaches, just steady performance.
STOP THE SWEAT DOME FOR GOOD

How the TrekAir Cap holds up after real miles
Still holds its shape after being stuffed in my bag.
Most hats I’ve owned crease or lose shape the second you fold them. I’ve thrown this TrekAir into my pack dozens of times and it always pops back into form. After weeks of trails, sweat, and sun, it hasn’t faded or stretched out. Looks sharp enough that I wore it straight from a hike into town.

No bounce, no slipping, even soaked in sweat.
I’ve had caps shift around every time I pick up pace, which drives me crazy. This one locks down without squeezing, and the sweatband really works. Nothing dripped in my eyes, even after hill repeats in August humidity. It’s the first cap I didn’t have to adjust once mid-run.
By Daniel P., 55, road runner from North Carolina
Doesn’t feel like a sauna on my head anymore.
Summers here usually mean cutting runs short because my old hats trapped so much heat. With the TrekAir, I can actually keep going. Airflow moves through and I don’t get that swampy, overheated feeling. First week wearing it I did a 12-mile long run and felt cooler than I have in years.
