I'm trying to remember what they are called, but I've made my hubby some "skull caps" out of fabrics like that. It's the fabric that fits between his head and the helmet. I like it because they are washable and prevent stinky head and helmet. I went to a bike shop and they were selling them for approx. $14. I made one for about a dollar.
I bought one on sale half price, deconstructed it, and made a pattern.
