This is a durable nylon messenger bag from Patagonia. It's incredibly large, so it can hold anything. It comes with a small bag inside, like a laptop case, which I think makes it very easy to use. I used it quite often, so please be aware that there is some dirt. Width: 52 cm Height: 49 cm Depth: 17 cm - Inner material: Nylon - Outer material: Nylon Thank you for looking.
