The ergonomic, waterproof Sea to Summit Sprint Drypack combines light weight with durability. Sea to Summit's design goal was to create a day pack that would be a hybrid of the best aspects of the Ultra-Sil Dry Day Pack and the 420D Dry Packs (Carve, Rapid and Flow). The main compartment of the Sprint utilizes a fully seam taped 210D TPU laminated fabric, while the base is made of a high abrasion-resistance 420D Nylon. The shoulder straps and back panel design are a lightweight version of the 420D harness style: besides great support and fit, they are ventilated to dry quickly. The non-wicking roll-top closure is fastened with Sea to Summit's patented Field Repair Buckle. Weighing only 14 oz with a 20-liter capacity, the Sprint is an ideal day hiking, bike commuting, peak bagging and long distance travel pack.
