The SuperStroke Carry Tube Accessory Sleeve is made with waterproof materials. It has quick-release straps at top and bottom to attach to your golf bag, (or you can remove the straps, and clip inside your bag) to protect your SuperStroke grip (not included) or your special club. NOTE: There is a honeycomb pattern in the canvas on the reverse side. Front side is smooth. The SuperStroke carrying sleeve is also perfect for those occasions when you want to just carry one club to get in some practice shots.
