Light as air, tough as your training. The On Running Lightweight Cap is designed for those who move—whether it’s a sunrise sprint, an all-day hike, or an urban adventure. Crafted from ultralight, breathable materials, it provides exceptional ventilation to keep you cool, no matter how intense the journey.

The moisture-wicking, quick-dry fabric ensures sweat never slows you down, while an adjustable strap offers a secure, custom fit for all-day comfort. For early risers and night runners, reflective detailing enhances visibility, adding an extra layer of safety when light is low. And when the weather shifts? This packable cap folds away effortlessly, ready to tuck into a pocket or bag.

From race day to rest day, the On Running Lightweight Cap is built for movement—wherever that takes you.
