The leather of this backpack is the strongest and most water-resistant we can find (full grain), and then we line it with pigskin, which is stronger than the cow skin. Functionality of this Leather Backpack This Leather Backpack with pockets has a floppy interior laptop back pocket. All three exterior pockets have a hidden pocket behind them for quick access and longer things. This includes the side pocket on each side. The lower d-rings on the bottom of the backpack are great for strapping on tripods, blankets, and wet river shoes. The shoulder straps are minimal, comfortable, and adjustable. In fact, you can remove the shoulder pads for whatever reason. Like if you are tying down something with a nice finish on the roof rack of your Land Cruiser and you don't want the rope to leave a mark. You can put this shoulder pad under the rope. I know there aren't many ways to innovate for functionality on a plain leather backpack, but when I found a chance, I took it.
