This year, our most rugged vest gets an upgrade with lighter materials and more water with every sip. The Ultra 10 was designed to endure one of the toughest trail races on earth: the Ultra Trail du Mont Blanc. This year, our most rugged vest gets an upgrade with even lighter materials and a 2-liter reservoir that delivers more water with every sip.
This pack is designed for self-supported adventures that don't shy away from mountainous terrain and unpredictable weather. It’s engineered to hold all the essentials, including food, shed layers, a headlamp, trekking poles, maps and more. The custom-fit harness and dual sternum straps adjust for a stable, comfortable fit, and the cargo compression lets you cinch everything down to minimize bulk.
