A backpack is useful for sightseeing, market visits and short walks, but packing another full-size bag can take up valuable suitcase room. Nanobag solves this travel problem with a foldable reusable bag that compresses into its attached pouch and opens into a hands-free backpack when needed. The Pack provides quick access through a drawstring closure, while the Daypack uses a YKK zipper to keep belongings secure. Both give travellers a separate place for water, snacks, light layers and purchases while allowing the main luggage to remain organized at the accommodation.
