As I moved about, the hat kept flopping into my eyes, and I have a big head. She sells a bathing cap style hat to wear under the hats, and that keeps them anchored, so I see that the $6.00 under hat is an essential part of the system. I also see that the "bathing cap" will mean all of my hats stay more easily in one place, and be more comfortable. You don't realize how much your hair does until it isn't there. So, today, everyone give their hair a big, cuddly hug, and say thank you for keeping your head warm, comfortable, safe, and anchoring your hats.
