I decided to try out the ShapeShifter, as it was on a BOGO sale. Now, I have not had a chance to try them out, but neither end of them are hemmed. It's just the raw microfiber fabric where the cuts were made. Am I supposed to believe this is going to hold up and not start fraying soon after starting to use them? This seems awfully chintzy, SweatVac. The fabric is thin, as the description indicates, but it is even thinner than I expected. The ad stated, "It's gaiter season!" in the middle of winter. I don't think these are going to keep my neck very warm. Good thing I mainly ordered for summer usage out in the Sun. Having now handled this item, I am glad I didn't pay $15 apiece. Even at $7.50 each, they are over priced, not to mention the shipping cost. I love your skull caps for cycling, but this product feels and looks cheap.
