Trion Zip 22L Backpack

Mammut made the Trion Zip 22 Backpack for day-long mountaineering adventures like multi-pitch climbs or ski tours with rappels. Its Contact Vent suspension system uses narrow, climbing-specific padding at the back panel, shoulder straps, and waist belt, and Mammut set the waist belt higher in order to accommodate harnesses more comfortably.

The Trion has an internal sleeve for hydration reservoirs and external straps for climbing ropes. Since the rope isn't in the pack, the Trion has enough room for a rack and climbing gear or avalanche safety essentials. Mammut reinforced the Trion's three-point haul system to carry up multi-pitches confidently. There are two stable carriers for ice axes, external and internal lid pockets, and compression straps to secure your gear on the ascent.
