Nanobag Daypack

The Nanobag Daypack is a foldable day pack made from diamond ripstop nylon that packs down into its own pocket-sized pouch. At 16 litres and just 33 g, it delivers a ratio of over 480 litres per kilogram — this is a just-in-case backup rather than a primary trekking pack. The build is frameless, with no chest or hip straps, closed with a YKK zipper and reinforced at stress points with bartack stitching. Despite the minimal weight, the manufacturer rates it for up to 30 kg of load, and the fabric carries a PFC-free DWR finish for light moisture resistance. It isn't meant to replace a proper hiking pack for full-day treks with water and extra gear — there's no hip belt, no compression straps, and no hydration bladder compatibility. Where it earns its place is as a packable backup for flights, a grab bag for errands on the trail, or a second pack for trips where every gram in the main luggage counts.
