OMM Nano 18 Rucksack

Jump to: Our Verdict / Features / Specifications

For fast hikes, one-bag travel, or everyday carry, the Nano 18 keeps it light, simple, and quietly capable.

Gregory says: 

The Nano 18 lets you pack for longer travel days and extended hikes. This minimal daypack features a large main compartment and quick access front zippered pocket for smaller items. A separate sleeve can be used to either put a hydration reservoir when you are going for a hike or to store a tablet or small laptop when heading into town, making this bag versatile for any outing.

Our Verdict

Light, neat, and built for movement, the Nano 18 is a strong performer for short hikes, travel, or everyday use when you don’t want to be weighed down.

At just over 500g, this 18-litre pack feels almost weightless on your back, yet still easily carries the essentials. The main compartment opens wide enough for a light shell, food, and extra layers, and I liked the addition of a separate sleeve for either a hydration bladder or tablet. There’s only one stretch mesh pocket on the side, but it held a 750ml bottle snugly and didn’t sag.

The front zip pocket is surprisingly roomy and has basic internal organisation – handy for keys and a snack bar. The back panel and straps breathe well, and the tuck-away hipbelt is nice, even if I rarely used it. Build quality is excellent; the fabric feels tough without being overbuilt.
