Sea x Sky Packable Waterproof Backpack

Big enough to hold a day trip’s worth of gear while remaining compressible and light enough to literally fit in your pocket when empty, the Sea x Sky Packable Waterproof Backpack is one item you’ll likely want to bring along on your next multi-day adventure. Its lightweight Cordura fabric is completely waterproof, complemented with an also-waterproof roll-top closure system to turn its main 24 litre storage compartment into a literal submersible dry bag. A 3M reflective zipper makes for a quick-access front pocket that’s still plenty good at keeping out rain, though, and plenty of other features — including an adjustable sternum strap, lightly padded and breathable shoulder straps with adjustable stability pulls, and two deep side pockets for water bottles and the like — mean you won’t need to sacrifice functionality for portability.
