The Ultra Chiller Shirt Drain Kit comes with 2 of our female free flow quick disconnects with a short length of tubing attached to each. You can blow gently into one of the connectors to clear the water out of your Ultra Chiller Liquid Cooled Shirt after each use. The connectors can also be used for the female side of a cool suit system if you need a spare (in a pinch, stop valve in them). Keep your Shirts Drain kit with you at the race track, just in case.
