On Ultra Vest 10L Unisex

With a 10-litre capacity, this high-performance vest was built for distances at the longer end of the ultra spectrum. Tested and trialed by ON’s elite team of trail athletes, its functional, modular design ensures a seamless experience on any trail, whether racing, training or chasing the high.

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 minimise bottle bounce for a smooth and comfortable ride.

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.
