Being a P.E. teacher and swim team coach, I live in headbands EVERY day. I've literally tried every headband out there and figured this would be another good one but not great. However, I was pleasantly surprised but how perfect these are! They do not move at all and are super comfortable. I sometimes go to bed forgetting I have one in. I've ordered about 10 of them now since they are the best headband I've ever tried and will continue as they get new ones in! :D
