You are looking at a Watershed 12200-ZD MEDIUM Utility Dry Bag with Zip Dry closure. It is New/Unused, but has a few dirty marks from storage. This bag is part of a larger system of bags that are issued out to not only the SEALs, but various SOF forces. This one is great size to use as a versatile general purpose bag and will take just about anything you can throw at it.
