Potentially the greatest invention in the history of fly fishing, the Fishpond River Rat 2.0 keeps your beer cold and your hands free.
The River Rat 2.0 has an insulating liner with laminated stretch mesh fabric that hold standard 12-ounce cans and bottles. While the nylon neck strap is awesome for when you are fishing, you can easily remove it and simply use the river rat as a standard coozy.
