TrekAir Ultralight Cap
Ultralight runners know the math: extra weight equals extra effort. And when your cap traps heat and sweat, it’s not just uncomfortable — it’s a steady leak on your pace, focus, and endurance.
TrekAir was built for the no-spare-grams mindset. Dual-layer mesh dumps heat as fast as you generate it. The featherlight frame disappears in motion, so you’re not carrying a drop more than you need. The clean 22–24" fit locks in without bounce or pinch, even on technical climbs or windy descents.
Tough enough to survive back-to-back long runs, minimal enough to disappear in your kit. No soaked crown. No shape collapse. No wasted energy.
UPF 50+ protection. Machine washable. Zero wasted grams.
- Dual-layer mesh vents heat instantly
- Feathery build saves energy every mile
- Clean 22–24" adjustable fit
- UPF 50+ blocks harsh sun
- Sweatband wicks moisture before it drips
