Review (4/5): Great for CPAP Headgear
I bought these to protect my hair when I'm sleeping with my CPAP machine. I'd been putting my hair in a pony tail before putting on the headgear, but this cap is actually easier and gives much better protection. I just put the cap on, let any hair not in the cap hang out below the cap, and put on the headgear. It stays on just fine because the headgear holds it on. It looks a lot better than a shower cap style silk or satin head covering too.
