Mammut Aenergy ST 20-25 Backpack
When touring the word lightweight should be lit up. Travel fast and light without saying goodbye to any of the bells and whistles we look for when choosing a pack. Inspired by trail running vests, this backpack was designed to keep the load close to your body, to prevent your gear from bouncing around. The front compression strap can be removed and worn as a hip belt for easier carrying, and the anatomically shaped shoulder straps bring even more comfort. Integrated helmet attachment, speed ski attachment, and rear access to the main compartment.
