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

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.
