A minimalist exterior belies the progression-packed nature of the 23-liter Crescent Peak 23L Backpack from Columbia Sportswear. When you're sweating it out on a steep uphill, your back will stay cool and dry thanks the Backdraft back panel—featuring directional foam conduits that allow hot air to rise and be replaced by cooler air. The Crescent Peak's innovative Techlite straps are comprised of an insanely strong, lightweight compound molded around super-breathing mesh inserts, with a healthy helping of cushioning for comfort. The exterior features water-shedding Omni-Shield®, as well as an integrated rain fly for when serious rainstorms descend. Water bottle pockets combine with 3-liter-hydration-unit compatibility to keep you hydrated, the sternum strap helps shoulder heavy loads.
