The Mamut Trea 35L Backpack is the pack you'll want your gear in whether you're scrambling to a summit or placing gear. It features numerous attachment points for gear--ranging from attachment points for extra carabiners to loops that 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.
