This product is a very durable, high quality bag. The hardware that closes the top is not cheap or flimsy, the fabric is thick, and the fabric handle is well-reinforced with stitches. When it's full, the shoulder strap feels a bit too high, causing the weight of the bag to dangle against your legs while walking. The top is not watertight, but would probably deflect most water in a rainstorm. The fabric seems like you could apply waterproofing material. This is a minor issue however. This product is great for college students, apartment dwellers, road-trippers, macho guys who wanna look tough with a military-style bag.
