Trion 18L Backpack

Take on your next vertical or semi-vertical adventure with the Mammut Trion 18L Backpack ensuring you have your gear within reach. This pack features enough space for a hydration reservoir, layers, snacks, and a few other luxuries while allowing you to climb, scramble, or hike freely and comfortably. Its anatomical shape makes it easier to reach upward, and it features a Contact Vent suspension system that lifts the load away from your back to promote airflow. 3D EVA foam provides cushion while ventilation channels encourage air to move around your torso. A rope attachment works with loops to secure all of your gear—from trekking poles to ice axes.
