Olive green nylon backpack. Outer fabric is mesh (double-layered, so it's not see-through and is water-resistant). Backing is nylon. Drawstring closure at the opening. Adjustable straps on the back. Two exterior pockets (with magnets inside. Gusseted bottom). One interior pocket (vertical). Approximately 44cm tall, 39cm wide, and 13cm deep at the base. Lightweight and soft fabric, so it can be made compact. Holds a lot more than it looks like it would.
