Kymit's 35L Motion Backpack is an all arounder that should keep up with your active days in the mountains, whether you're climbing crags or spending a night in the woods. This backpack features Klymit's unique Air Frame Technology that uses an air pad to conform to your back's movements. You can pump this air pad up or down for customized comfort. Klymit made the Motion out of durable yet light nylon fabrics and coated the pack in silicone for reliable water resistance. The Motion also features a zippered top panel that opens the main compartment wider than traditional entries. There's a hydration port for your own reservoir, and the side pockets stow water bottles while the zippered front pocket stores an easy to access layer. Compression straps secure your load on long treks into the wilderness.
