Description
The Aenergy ST 20-25 by Mammut is an ultralight and technical backpack, ideal for fast ski mountaineering and day trips where every gram counts. Its construction is inspired by trail running vests, featuring wide shoulder straps and mesh pockets that provide a snug fit and immediate access to small essential items. Made from 100% durable polyamide, this backpack stands out for its exceptional functionality in a minimalist design. Access to the main compartment is possible both from the roll-top closure with zipper and, even more practically, through a large rear zipper that allows you to reach all the contents without having to remove the externally attached gear. A dedicated front pocket allows for safe and accessible storage of avalanche safety equipment. Versatility is ensured by a quick transport system for skis, an integrated helmet holder, a rope attachment, and removable compression straps, which can also be used as a lumbar belt to further stabilize the load.
