Review title is Almost Exactly What I Wanted [SEP] Looking for something to cover my hair so my cpap headgear quits crimping the hair all over the place. Really tough to get it to "calm" down and lay right sometimes. This cap does keep my hair in place, BUT my big 'O head isn't very comfortable! Really need some bigger sizes made available. This one leaves a pretty good indent across my forehead that takes quite awhile to go away after getting up. The elastic band needs to be bigger! NOT the actual head covering piece...it's perfect! Breathable and keeps the hair from getting bent all over by the cpap strap.
