I found cute lightweight caps on Amazon and ebay. Search for pre-tied chemo scarves and chemo caps. They were soft, stretchy, and very comfortable. I loved a cotton bamboo one. Some had ribbon "roses" and such on the back. I loved them... I had them in all kinds of different colors to match my clothes.
