no stretch and so tiny i think they were made for children [SEP] these things are tight i feel like my head is getting compressed wearing them it is disappointing because i thought they were kind of expensive and now i cannot use them the fabric they used does not have any stretch to it they are so tiny i think they would be comfortable on children adults would feel extreme discomfort just having it on and a hard time fitting it around their head i almost could not make it around my head putting it on it is about the size of my neck i wish i would never bought them it is a waste of money on something i do not like
