Mammut Trion Nordwand 15L Backpack Arumita, One Size

Mammut's Trion Nordwand 15 is a lightweight, alpine backpack with a unique design that melds the look and feel of a running vest with a technical daypack. That keeps our kit close to our body for better balance, freedom of movement, and a compact build to squeeze through nooks and crannies. The large mesh pockets on the shoulder straps keep our hydration flasks and bottles close at hand while we can also carry rope and additional gear with external attachment points.
