The Mammut Trion 35L Backpack is ready for your technical days in the mountains. It features numerous attachment points and organization options, including a place to secure your trekking poles or ice tools. The entire back panel zips open for full access to your layers, food, water, and other gear, while a front pocket secures and organizes your avalanche safety equipment. A strap below the brain evenly secures your coiled rope across the pack, expanding your gear-carrying capabilities so you don't need to bring an extra rope bag.
