You can get the Arctic Yowie, which is fleece lined, or just the Yowie, which is a very thin, flexible material. I've never tried the Arctic Yowie, but I have 2 Yowies and they're comfortable. I don't like using them as a beanie though, I never really figured out how to do it right so when I make it into a beanie it sucks. But I love it as a facemask bandana type thing. They are way better than bandanas.
