these run small not recommended for lots of hair [SEP] i have not used these yet but right out of the package i know that they run small these are not for girls women with a lot of hair and i will just say it or if you have a big head basically there is a small thin plastic like cap kinda like a thinner version of what you know a generic shower cap to be with an elastic band sewn to a satiny cap i was not expecting satiny i have yet to use them but just know that they run small i only purchased them so that i could shower while heavily conditioning my very fine and thinning locks
