The Sea to Summit Expedition Duffle Bag with Backpack Straps is a rugged, load-hauling duffle bag backpack for rough-and-tough expeditions, overlanding adventures, and surviving the urban jungle. Features three carry modes: classic hand grip with magnets to keep straps together, single strap mode, or backpack mode. Straps can also be stowed when checking bags. This ultra-tough travel and gear bag is made from waterproof tarpaulin laminate, with a super-durable 1000D nylon base, and a theft-resistant double-toothed zipper. Steel gated hooks manage the straps. A padded lid opens extra wide for easy packing, and there is a large internal zipper pocket for organization. Lash points make it easy to attach the bag to vehicles or pack animals. The Sea to Summit Expedition Duffle Bag is available in four sizes: 45 Liter bag is carry on size, 65 Liter bag is perfect for a long weekend, 90 Liter bag holds clothes and gear for a longer trip, and the 130 bag has room for everything. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.
