The On Ultra Belt 2L is built for runners who want to carry the essentials without wearing a hydration vest. Designed for trail running, racing and long training days, it sits securely against the body with four-way stretch construction that moves naturally with you over technical terrain.

With 2 litres of storage and an included 500ml Hydrapak® Soft Flask, there's room for hydration, nutrition, your phone, keys and other essentials. Elastic mesh pockets provide quick access on the move, while rear bungee cords securely carry collapsible running poles when the trail gets steeper.

A fully ventilated mesh construction helps keep you cool, while targeted padding reduces pressure points for long-lasting comfort. Whether you're tackling local Wollongong trails or lining up for your next ultra marathon, the Ultra Belt 2L offers a streamlined alternative to a running vest when you need to travel light.
