Rab Muon 40L Hiking Pack

Designed to minimise weight and maximise time on the trail, the Muon is an ideal choice for long-distance thru-hiking and trekking with a carefully refined kit list. Constructed from ultralight yet exceptionally durable fabric, this pack ensures excess weight is kept to a minimum while maintaining the strength required to support heavy loads with impressive stability. Streamlined and versatile, it effortlessly adapts to different needs—whether carrying additional gear, increasing speed, or covering greater distances.

In addition to its lightweight and robust construction, the Spectra® Ripstop fabric offers UV resistance, making it well-suited for high-altitude hiking. The close-fitting TRI-FLEX™ carry system incorporates a wraparound harness, a contoured lumbar pad, and a supportive hipbelt, all working together to provide enduring comfort across extended treks. The fit can be fine-tuned with the forward-pull hipbelt, which, in combination with the ultralight compression straps, ensures a stable and balanced load. The lower compression strap also doubles as a convenient storage option, ideal for securing a roll mat.

Accessing gear is quick and effortless, thanks to the roll-top closure, which allows the pack to expand for larger loads and compress as supplies are used. A generous front stash pocket accommodates extra layers, while side stash pockets and harness pockets keep water and snacks within easy reach. Inside, there is room for a 3L hydration bladder, and trekking poles can be securely attached to the exterior when hands need to remain free.
