Width: 33cm Height: 40cm Pouch Height: 13cm Depth: 14cm Material: Nylon Color: Black The lower part of the backpack can be removed and used as a shoulder bag. The backpack and shoulder bag are secured with Velcro and buckles. The shoulder bag part is waterproof, making it convenient for storing wet clothes or food and drinks. The side mesh pockets have one side with a drawstring and the other with Velcro. There is also a mesh pocket on the front of the shoulder strap. The material is thin. When taking photos, it is stuffed to show the shape, but without anything inside, it is almost flat and will not stand on its own. I thought it would be convenient for travel and picnics, but I ended up not using it.
