The Trion Light 38 is an all-rounder for your back. The backpacks in the Mammut Trion Light family have been developed as versatile and extremely light alpine backpacks. The 38+ version is very versatile and, unlike the 28+ model, features a classic flap. However, the overall back length of 55 cm has been designed specifically for climbing and mountaineering. Even with a heavy load, the backpack sits compactly on your back, allowing you to easily tilt your head back when climbing and belaying, even when wearing a helmet.
