The Muon ND 40L Backpack is designed for long-distance hiking and trekking, minimizing weight while maintaining durability. It features ultralight Spectra® Ripstop fabric that is UV-resistant, and a TRI-FLEX™ carry system with a wraparound harness, shaped lumbar pad, and supportive hipbelt for stable, comfortable load carrying. The roll-top opening allows for flexible pack expansion. It includes front and side stash pockets, harness pockets, and space for a 3L hydration bladder. Narrower dimensions make it suitable for women or smaller frames.
