Mammut Trion 28L Backpack in White / Black

What Our Gearhead(R) Experts Are Saying:"The roll-top lets me compress it down on the approach and open it back up when I'm shedding layers or strapping on crampons, and the side zip means I'm not digging through the top to grab something mid-route."Why We Like ItThe Trion 28L handles ski tours, climbs, and mountaineering trips with a construction built for the rigors of each.

Designed with input from Mammut's top alpine athletes, the pack is comfortable and feature-loaded.

The contact back system transfers load well while allowing on-the-go fit adjustments, and the dedicated avalanche equipment compartment keeps safety gear organized and accessible when conditions change fast.
