Rab Muon Rucksacks

Jun 27, 2024

Minimising weight so you can maximise your time on the trail, the Muon is the ideal companion for long distance thru-hiking and trekking with a refined kit list. The ultralight, ultra-tough fabric and lightweight back system keep excess weight down and are exceptionally strong, capable of supporting heavy loads with superb stability. Versatile and streamlined, the pack adapts to your needs, whether you’re looking to pack more gear, pick up the pace, or clock more miles.

Our Verdict

The Muon backpack from Rab is a pinnacle of innovation. Constructed from Spectra® Ripstop, a fabric renowned for its exceptional durability and lightweight nature, it embodies the fusion of cutting-edge materials and thoughtful design.

 

Spectra® Ripstop Technology integrates a robust grid of polyethene fibers within a 210 Cordura nylon structure, yielding a material that is incredibly strong and remarkably lightweight. Moreover, with 85% of its content derived from recycled materials, the Muon is committed to sustainability without compromising performance.

 

The TRI-FLEX™ carry system, featuring a shaped lumbar pad, wrap-around harness, and supportive hip belt, represents a pinnacle of ergonomic engineering. It is designed to sit snugly against the wearer's back and facilitates unhindered movement and stability even under heavy loads, ensuring comfort during extended treks. The adjustable hip belt, equipped with a forward pull mechanism, allows for effortless customisation, while the inclusion of ultralight compression straps aids in load stabilisation and versatility.

Practicality defines the Muon's design, with features meticulously crafted to enhance functionality and convenience. The fixed back length ensures a consistent fit, while the adjustable hip belt optimises weight distribution, reducing strain on the back and spine. The removable lid offers adaptability, allowing users to shed excess weight as needed.

 

The Muon has an array of pockets strategically placed for accessibility and efficiency. From the two pockets in the lid to the large front stash and side mesh pockets, every inch of space is maximised for storage, ensuring essentials are readily available when needed. The shoulder strap pockets are a great addition to the rucksack, enhancing accessibility and permitting quick access to essential items like mobile phones and snacks. This trend of integrating shoulder strap pockets to rucksacks is also commendable.

Furthermore, the Muon easily accommodates additional gear, featuring external attachment points for walking poles and compatibility with hydration bladders. The thoughtful incorporation of dual exit options for hydration hoses adds flexibility, while the collapsible pole carry system underscores the pack's adaptability to diverse outdoor pursuits.

 

In essence, the Muon epitomises the marriage of innovation and practicality, offering outdoor enthusiasts an excellent backpacking experience. Whether embarking on long-distance thru-hikes, overnight excursions, or weekend mountain trips, the Muon is a reliable companion, enabling explorers to push boundaries and maximise their time in the great outdoors. - Reviewed by Ultralight Outdoor Gear
