I've lost a beanie and my second one also kept coming off. I've gone to the neoprene do-rag. mine has some kind of bumps on the forehead edge thst helps keep it in place. also poked a couple of small holes in the piece thst lays over the top of my head. have had no further problems with it floating up a bit.
What's the name of this product? As I said, my Scuba Do Rag tends to slip off. I'd like to try a neoprene do-rag.
