Denali 100L Backpack

With a cavernous 6102 cubic inches of space, the Gregory Denali 100 Backpack is designed for long alpine climbs, week-long Alaskan glacier trips, and gear-intensive expeditions. It's nearly identical to the Denali 75, but it'll be the better choice when we leave civilization behind for a week to ski big lines and climb big walls from a remote basecamp. To keep Denali light, Gregory designed the Denali with a lighter 210D nylon fabric and hooked it up with 420D high-density reinforcements where they are needed most. A puncture-resistant, internally laminated front panel protects against ice axes, crampons, and ski edges, while the 630D high-density nylon base saves the bottom of the pack from rock and ice. There's also a dual-entry pocket on the front panel that can hold crampons or a shell for easy access.

Gregory fitted the pack with its top-of-the-line Fusion Flex Pro suspension to keep it comfortable when weighed down with expedition-grade loads. The system is composed of two 7075 aluminum frame stays that can be removed to lighten the load, as well as a sewn-in frame sheet for additional support and to prevent gear from poking through. A tubular cross-stay prevents the bag from collapsing and bunching when weighed down with a heavy load, and the high-density EVA foam padding at the shoulders, back, and hip pads ensure a comfortable fit. There's a removable bivy pad concealed in the back panel, and the hip belt can also be removed when we're really trying to go fast and light in the high alpine.
