ON Ultra Cap

🧢 Ultralight comfort for long trail runs in the mountains

During long trail runs, you don't want anything to bother you – especially not your cap. The On Ultra Cap It is so light and breathable that you almost forget you are wearing it. Developed for warm, intense runs in the mountains, where focus and comfort make the difference.

With its soft visor, smart ventilation, and quick-drying sweatband, this cap keeps your head cool and your vision clear, even when the pace picks up.

🌬️ Stay cool when things get tough

The mesh side panels and subtle laser perforations on top ensure constant airflow. Heat escapes, fresh air enters. Ideal for long climbs, sunny trails, and summer conditions.

🪶 So light that you forget it

With only 35 grams is this one of the lightest trail caps you can wear. No stiff materials, no pressure points – just a soft, comfortable fit that moves with every step.

💦 No sweat in your eyes
