Backpack Depth: 12.5 cm Height: 41.5 cm Width: 30 cm Black with blue lines. Lightweight. Left side has space for a 500ml water bottle. Right side has three lines for attaching carabiners or keychains. There are also lines on the lower front and one place on the upper front for hanging items. Main zipper is a double zipper. Front has a pocket with a zipper. Inside, there are two pockets. The shoulder straps are adjustable. I'm selling it because I don't use it anymore. It's small and light, so it might be good for children.
