Mammut Aenergy ST

With this lightweight ski touring backpack, you'll be effective on the snow without sacrificing comfort, durability or features. Inspired by the design of a trail running vest, the ergonomic suspension system guarantees a tight fit without restriction, keeping the load stable and close to your back. The compression straps can also be converted into a hip belt. Almost all compartments are accessible when on the move and you can access the main compartment through the back opening. For climbing passages you can attach your skis diagonally without removing the backpack. Besides the special compartment for avalanche equipment, features like the rope holder and holders for an ice axe, trekking poles and helmet make the 20- to 25-liter-volume Aenergy ST a backpack for ambitious ski touring without compromise.
