A lightweight, 5-litre trail running vest for short-medium distances. Includes a built-in hydration system and customisable fit.

Tested by the best

With a 5-liter capacity, this high-performance vest was built for shorter distances. Tested and trialed by our elite team of trail athletes, its thoughtful, minimalist design ensures a seamless experience on any trail, whether racing, training or chasing the high.

Optimized for stability

Ultralight yet tough, the breathable mesh material is tailored to provide a precise fit that stays put, while the patented-pending closure system allows you to adjust the vest's placement to best suit your body. Non-stretch materials minimize bottle bounce for a smooth and comfortable ride.

Easy access to essentials

With two 500 ml Hydrapak® flasks for water, plenty of pockets and a simple fastening system that tightens, the Ultra Vest is packed with all the essentials – and then some. Think additional daisy chain loops that are strategically placed to allow you to attach your poles or quiver bag.
