Lightweight | Durable | Built to go the distance

Designed for serious miles on the trail, the Rab Women's Muon ND50L is a thru-hiker’s dream. Crafted with ultra-tough, UV-resistant Spectra® Ripstop fabric, this pack balances rugged durability with ultralight performance—perfect for extended treks, high-alpine routes, or minimalist overnights.

Its TRI-FLEX™ carry system is engineered for all-day comfort with a wraparound harness, shaped lumbar pad, and padded hipbelt that hugs your frame without weighing you down. Tailored for women and those with smaller builds, the Muon ND50 ensures a secure, stable fit even on tough terrain.

The 50L main compartment expands and compresses with your gear thanks to a smart drawstring closure, while the removable lid gives you weight-saving flexibility. Multiple pockets—including dual harness stash pockets, side stretch pockets, and a large front dump zone—keep snacks, layers, and maps close at hand. A 3L hydration sleeve with dual exit ports and external pole carry add even more trail-ready convenience.

Best for: Multi-day backpacking trips, high-mileage thru-hikes, and long alpine treks where weight and comfort matter most.
