Vinyl-type material graphic bag. Joe Boxer, 2001. In EUC for the age. Backpack straps are 30" long at the largest adjustment. Backpack does have blue ink stains in various parts, sort of like when your denim/jeans rub off on other clothing. It was this way when I purchased it secondhand and it bothered me none. Measurements shown in photos, as well as slight imperfection at the bottom of the bag where the piping has worn. Please ask questions before purchase to ensure you are getting an item you love! :)
