On Ultra Belt 2L Unisex
A lightweight trail essential built for big missions with small fuss. The On Ultra Belt 2L delivers sleek, bounce-free storage with room for everything you need and nothing you don’t.
Crafted from ultra-breathable 360° stretch mesh, it moves with your body to stay secure on climbs, descents, and long miles in between. With smart compartments for hydration, nutrition, and gear, it keeps your essentials close without getting in the way.
Includes a 500ml Hydrapak Soft Flask, with a locking nozzle and easy-grab design. External bungees at the back carry poles, while front and side pockets give you easy access to gels, phone, or extra layers. Reflective trim adds visibility for early starts and late finishes.
Minimal weight, maximum function. Built to go the distance.
Why You’ll Love It
Jake – Staff Member and Athlete
I was genuinely surprised by how well it hugs the body without riding up or bouncing. It feels secure but still breathable, and there’s way more storage than you’d expect just looking at it.
