This mini-sized backpack for adults is perfect for a wide range of uses, from daily use to travel. While simple, it features a design that clearly demonstrates Isaac's unique attention to detail, such as the design of the zipper end and the original logo engraved on the metal fittings. It's also made of soft and lightweight nylon taffeta. The main zipper is designed with a gentle, straight line, rather than the sharp curves found on regular backpacks, to allow for smooth opening and closing.
