A lightweight, 10-liter trail running vest for long distances with a built-in hydration system and removable dry pack.


Tested by the best
With a 10-liter capacity, this high-performance vest was built for distances at the longer end of the ultra spectrum. Tested and trialed by our elite team of trail athletes, its functional, modular 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 and adjustable hem allow you to adapt 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 BPA-free Hydrapak flasks, a detachable 5L dry pack and space for a hydration bladder on the back, the Ultra Vest 10L is packed with all the essentials and then some. Think additional daisy chain loops and modular attachment for your poles or quiver bag, plus a zippered card pocket on the back.
