Reduces friction (and distractions)

Part of On’s Ultra collection for elite trail racing, this is one of their most innovative protective layers. Moisture-wicking materials keep the dirt and water away, so you only have to focus on the trail ahead. And the motion-inspired design reduces friction for zero distractions.

Waterproof performance

Running-inspired but made for the trails, the Ultra Jacket is your waterproof hero. It’s light enough that it won’t weigh you down and packable when you need to remove an extra layer via a small pouch at the back of its hood.

Reflective details

Equipped with the right features to tackle any terrain, premium reflective elements mean you’ll stand out after the sun goes down. Plus, two pleats at the back allow you to wear it with a running vest or small backpack for all your trail essentials.
