Review title is Not great [SEP] These are one layer of a plasticky material, not two layers with a waterproof inner layer and fabric outer layer like most non-disposable shower caps. They are not adjustable at all; the giant bow in front is purely decorative and gets in the way of washing your face, so I cut it off. They're also pretty small; they're only elasticized in the back, and it's hard to stretch them over your bun and basically impossible to get all of your  hair under it at the sides and back. They're adequate but not any better than a cheap disposable one. I'll probably end up throwing them out as soon as I can find a better one.
