I LOVE this balaclava! It's thin, but it's warm and more wind resistant than I thought it would be. I have been wearing this on the bike trail on below zero windchill days and it keeps my face warm. I wear a MH windstopper hat on top and my ears stay nice and toasty. Like other reviewers have mentioned, I love that I can pull it down and uncover my entire face or use it as a neck gaitor. I like to periodically uncover my face and some of the other brands are thicker and too tight to be comfortable when I pull it down under my chin. I do get some fogging on my sunglasses, but not as much as with the synthetic balaclavas. I would buy more of these if they were in stock. Highly recommend.
