I bought two of these caps for my mom who is losing her hair to chemo. She's been complimented SO much on these caps by her visitors, nurses, and doctors! One nurse even asked for the Amazon link to buy some for someone she knows. They fit my mom perfectly and are easy for her to get on and off even while she's very weak. They also seem to stay in place fairly well while she sleeps. I am super happy with my purchase. Anything that makes my mom feel good about herself right now is 100% worth the money!
