Unisex On Running Ultra Vest 10L

The long-anticipated On Running running vest is finally here! This 10-litre vest is purpose-built for long distances running and comes complete with a built-in hydration system and a removable dry pack.

Designed and tested with the On elite team of trail athletes, its functional and modular design guarantees a seamless experience, whether you're racing, training, or simply chasing that natural high on the trail.

This vest is all about being ultra-light yet incredibly tough. Crafted from breathable mesh material, it provides a snug and secure fit that won't budge.
