This small Cozy Keeper is our version of, forgive the expression, a 'pooh bag' holder. It is ultra light, stretchy, and fastens easily to your uLeash. Made out of the same materials as a wet suit, it is meant to get damp, this way you can wash it and keep it clean and sanitary. No more carrying around those plastic bags to clean up after your dog makes a mess! Just fill your Cozy Keeper with your roll of pooh bags, or whatever else you want to put in there like sunscreen, chapstick, a mini flash light, keys, a lighter, or some dog treats. They measure 1 3/4" wide by 5" long. Normally $10, you can add a Cozy Keeper to any uLeash for half the price, only $5! You'll love it.
