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's disappointing because I thought they were kind of expensive and now I can't use them. The fabric they used does not have any stretch to it. They are so tiny I think they'd be comfortable on children. Adults would feel extreme discomfort just having it on and a hard time fitting it around their head. I almost couldn't make it around my head putting it on, it's about the size of my neck. I wish I'd never bought them. It's a waste of money on something I don't like.
