The material is the classic and traditional KS-100e. Made from 1000-denier high-strength nylon with a PU coating, its durability and cotton-like texture enhance the classic taste. It has a zippered mesh pocket inside, a zippered pocket on the outside, and a zippered pocket on the rain cover. Zippered pockets are also located on both sides of the hip belt to support the load. Padded material is included on the back and around the waist. It will be a great help for day hikes and town use. This is a rare, anniversary-limited Karrimor backpack. How about it? It was used once for a short time and then stored. It is clean with no noticeable scratches. Thank you very much! ^_^
