The product is well made and would probably be great for its intended use. I was hoping it would keep my big ears pinned down when I pull my helmet over my mellon. It works to some degree for this. If you don't mind the skull cap being very stretchy, then it will be right for you. One size will fit all.
Ok so i guess i was expecting a little more. Really all it is is a do-rag that covers your ears. I did keep it and yes i do-rag wear it. It does keep my hair in check but as for sweat yup like nothing was there still a nice wet helmet. As for fit it is a little small, if your heads much more than 24'' probably not going to fit very well.
