Columbia backpack. Thin canvas-like material for maximum durability. Fits SO much, more than you would expect. In nearly new condition, no signs of damage. Has a small zip pocket for small items like keys, wallet, etc. The main pocket is just one big opening with a drawstring. All the tan/brown material is a suede like leather for more durability. Color description: slate grey with a hint of blue? Hard to describe, the lighting in the photo makes it look darker blue than it is. The leathery sections are tan.
