Built for fast ski tours, the Mammut Aenergy ST 20-25 lets you travel light and fast without compromising comfort or useful features. The carrying system is inspired by trail running vests. The load is kept close to the body to prevent it from bouncing around, while the anatomically shaped shoulder straps improve wearing comfort. An elastic chest strap ensures a firm fit while still allowing you to breathe easily. The front compression strap can be removed and worn as a hip belt.

　　Most of the pockets are always accessible, and you can attach your skis without having to take off the pack. Rear access to the main compartment puts everything right at your fingertips. The separate front compartment is for your avalanche safety equipment. To top it all off, this all-star pack has features like an integrated helmet attachment, rope attachment and loops for ice axe and poles. With the Aenergy ST 20-25, you can charge straight to the summit, leaving others in the dust.
