The Patagonia 45L Cragsmith Pack is built with 100% postconsumer recycled nylon plain weave fabric featuring a PU coating and a durable water repellent finish made without intentionally added PFAS, and it includes ample foam padding throughout to protect gear from all angles. A convenient U-shaped lid offers easy top access, while the back panel fully opens for complete entry to the main compartment. Two large exterior stretch pockets hold bottles or guidebooks, and a deep zippered lid pocket with an internal zippered pocket keeps essentials secure. The load-carrying system includes breathable mesh shoulder straps and a back panel, a padded waistbelt, an adjustable sternum strap, and load lifters, and it is finished with a reinforced top-mounted haul handle.
