The heat-molded BioForm™ harness and hipbelt provides a precise customized fit to ensure all day comfort and a mesh backpanel keeps you cool if the temps heat up as you climb out of the deep arroyo. The top of the pack is a dual compartment that can also be removed to save weight or converted into a lumbar pack for summit dashes. Two zippered hipbelt pockets keep your phone, snacks and other essential items organized and close at hand. External stretch mesh pockets—two side and one rear—allow more grab and go storage options. The external hydration sleeve allows easy access to make liquid refills a snap. There are dual ice axe loops from alpine adventures and the Stow-on-the-Go™ trekking pole storage system lets you stash your sticks without breaking stride.
