Mammut - Trion Light Backpack

Availability: Out of stock

Stock #: 131E-

When you head out for an alpine climb, you probably carry just the essentials to save weight. The Mammut Trion Light operates on the same principle: at 1,004 grams of total weight for the 40-liter version, it's the lightest alpine winter backpack in the Mammut range. Its patented butterfly™ suspension system guarantees optimal load transfer and allows the upper body complete freedom of movement thanks to the pivoting hipbelt, which is also removable so you can shave even more weight from the pack when your load is light.
