This Review Title is Good fit, big buttons and the content is: The buttons are not sturdily sewed right the headband. I have others with large buttons that support my large banded masks, these did not. The button flopped forward and the mask slipped off. It worked much better with the thin banded masks..There are other information for this review, one is This reviewer did not purchase it and the other is 0 people think this review is helpful.
