Charles, this cuff has a button on the back. I first thought it could be for a loop attached to the bottom of Storm cap which would have made sense. I sent Wade off an E mail. He has not seen a Storm cap with lower loop. They do have one on the top of Cap. Maybe next idea could be to hang that off quiver? No clue, and it's a guessing game right now. None of the Catalogs that I have searched through are showing a button on the back of cuff like this one. Enjoying the research ;-)
