Like a good climbing partner, you need to be able to depend on your gear to hold up in the alpine. Designed to withstand surly mountain weather, the Mammut Trea Guide 40 Plus 7 Backpack won't fail when the stakes are high. Maintaining all the features of Mammut's more technical alpine packs, the Trea Guide features a women specific fit along with the Motion Butterfly suspension system and a supportive aluminum frame. The hip belt can be removed when wearing the pack with a harness, and the lid can be heightened to make room for extra gear as needed. An internal sleeve accommodates a hydration bladder, while gear loops along the front of the pack secure ice axes, skis, and trekking poles for the approach.
