ASSOS x Mammut Aenergy TR5 Vest

The ASSOS x Mammut Aenergy TR5 Vest is an ultralight trail necessity, engineered with hydration-system compatibility, expanded storage for essentials, and two soft-flask holders (flasks included).

Built for pure performance, the Aenergy TR5 provides all the storage, hydration options, and versatility needed for trail running, mountain training, and cycling. The harness micro-adjusts for security that eliminates bouncing, and the storage options include a secure zippered pocket, drop-in pockets for gels, and a trekking-pole carrier. Flask sleeves – including the flasks – further expand fueling options, and an integrated hydration sleeve stashes a bladder.
