For fast-moving hikers pounding out the miles, this strong, streamlined pack is built to keep weight down, with ultralight features allowing you to pack more kit and cover longer distances.

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.

As well as being durable and lightweight, the Spectra® Ripstop fabric is UV-resistant, perfect for hiking at high altitudes. The close-fitting TRI-FLEX™ carry system features a wraparound harness, shaped lumbar pad, and supportive hipbelt, providing reliable comfort that endures over long distances. You can adjust the fit using the forward pull hipbelt, which, along with the ultralight compression straps, helps to stabilise your load. The lower compression strap doubles up as storage, perfect for stowing your roll mat.

Grab kit quickly and easily with the simple roll top opening, which allows the pack to expand with larger loads and compress as you work through supplies. The large front stash swallows up extra layers, while side stash pockets and harness pockets provide on-the-go access to water and snacks. There’s also space for a 3L hydration bladder inside, and poles can be fixed to the outside of the pack when you need to keep your hands free.

Built with narrower dimensions, the Muon ND40 is ideal for women or those with smaller frames.
