Camouflage nylon body bag, functional with a mesh pocket. I think it's the perfect size for an elementary school boy to carry. - Design: Camouflage pattern - Material: Nylon - Features: With mesh pocket - Zippers: Double zippers - Straps: Adjustable shoulder strap Thank you for viewing. The back is mesh, so it's very breathable. It can hold a Switch, smartphone, and wallet. I've only used it a few times, so the condition is not bad. I bought it at Aeon.
