[Manager's comment]
This lightweight backpack is the sister of the Muon 40. Recommended for camping in tents and huts, Rab has released a new backpack! It was released in 2024 and became a hot topic. Despite its 40L capacity and built-in frame, it weighs just 895g, less than 1kg! It's perfect for those transitioning from a basic hiking style to an ultralight (UL) backpack! Those accustomed to UL backpacks will be amazed at how comfortable it is, and those who use backpacks weighing over 1kg will be impressed by its lightness!
This backpack is great in every respect: lightweight, comfortable to wear, stable, and affordable.
[Size]
Recommended for petite people (under 160cm). The standard model is Muon 40.
[Product introduction (excerpt from manufacturer)]
Minimizing weight and maximizing time on the trail, the Muon is the ideal companion for long-distance thru-hikes and sophisticated treks. Its ultralight, ultra-tough fabrics and lightweight back system keep excess weight to a minimum while providing exceptional stability to support heavy loads. Versatile and streamlined, this pack adapts to your needs—whether you want to pack more gear, pick up the pace, or cover more distance.
【Features】
Durable, lightweight, and UV-resistant, Spectra® Ripstop fabric is ideal for high-altitude hiking. The form-fitting TRI-FLEX™ carry system, with its wraparound harness, shaped lumbar pad, and supportive hipbelt, provides dependable comfort for long distances. The forward-pull hipbelt allows for an adjustable fit and, along with ultralight compression straps, helps stabilize the load. The lower compression straps double as a storage compartment, making them ideal for storing a rolled mat.
【moreover!】
A simple roll-top design allows for quick and easy access to your gear, a large front mesh pocket stows an extra layer, side mesh pockets and a harness pocket provide quick access to water and snacks, there's even space inside for a 3L hydration pack, and the poles can be secured to the outside of the pack for hands-free use.
