Of all the different masks I've tried (6 so far), this is the best one. I am a 6'2" 230lb man with a short beard, a big nose, and glasses. The large size fits me perfectly, covering well past my chin and doesn't fog up my glasses when the nose is adjusted properly. The chambray fabric is a bit more comfortable for me, but the cotton flannel feels nice too. Not scratchy and not too warm. The ear bands are soft and comfortable to wear for hours, even with glasses. Simply put I have no complaints and intend to purchase several more.
