This was bought by my son a few years ago, but I've been using it. There are no noticeable stains or scratches, and the inside is very clean. It's lightweight and has many storage pockets, making it convenient to take things in and out from the top and sides. It has a breathable mesh back and straps! The size can be adjusted with plenty of length. Size: Body circumference: Approximately 80 cm Body height: Approximately 42 cm Gusset: Approximately 13 cm The stylish color scheme can be used by both men and women.
