comfortable on larger heads [SEP] i love these because they come in several pretty colors go with any of my scrubs adjust to larger heads nicelyon the loosest setting the buttons fall above slightly in front of my ears that is exactly where i want them because not only are most masks too hot tight uncomfortable but they make my feel like i am trying to breathe while someone is holding a pillow over my face so these actually help me to breathe also i just wish they also offered wider adjustable headbands with buttons also most wide headbands are just too tight painful on me
