If you're looking for a pack for your next trip to high altitudes and gnarly terrain, the Mammut Trion Zip 42L Backpack is a balanced option that boasts plenty of features and a design that lets you carry heavy loads with comfort. Designed for climbing and mountaineering trips, this pack features a V-Frame load system, which utilizes a lightweight aluminum structure for effective support and allows for freedom of movement during long approaches. Cushioned back padding adds comfort on the trail, and a detachable, low-profile hip belt delivers added support when you need it. And for those big wall missions you've got a reinforced three-point haul system that lets you easily lug your pack up after you. It wouldn't be a good pack if it didn't hold everything you need it to, and the Trion has plenty of storage options for your essential pieces of gear. The flap features a handy rope attachment for your technical ascents, and there's also a set of ice-axe attachment points in case those ascents take place in frigid winter conditions. Daisy chains and compression straps hold any other gear and layers you need quick access to, and the easy top-loading system will let you access all of your other important items.
