When your expedition takes you from rushing rapids to rugged portage trails, the SealLine Pro Pack Dry Bag delivers bombproof waterproof protection with the comfort of a premium backpack. This 70L expedition workhorse transforms from a sealed fortress protecting your gear during big river running into a seriously comfortable pack for those inevitable long portages between waterways. The removable harness system features a full-length framesheet, lumbar padding, and breathable back panel that transfers weight to your hips, making even heavy loads manageable on multi-day wilderness adventures. Built tough with welded seams, a reinforced bathtub bottom that laughs off rocky landings, and an intuitive DrySeal roll-top closure, this is the gear you reach for when failure isn't an option and your back will thank you for the upgrade from a basic dry bag slung over your shoulder.
