Ace's Gadgetable business backpack. The material is Cordura Ballistic. I used it for about a year. Product number: 62362 The stitching of the zipper on the outer front pocket is partially detached (Photos 5 and 6). The zipper can be opened and closed without any problems if you slowly pass it through that part. Otherwise, it is relatively clean. Except for the stitching of the zipper on the outer front pocket, there are no noticeable scratches or stains, but please purchase only if you understand that this is a home-stored, used item.
