You can get a thermal lens for just about any mask, just whatever you do, dont use anything other than water or antifog lens cleaner. Windex will destroy the thermal layer on the lense, something I learned not too long ago. When I sprayed it on there you could see the thermal layer start to wrinkle up on the lense I was horrified. So I ended up using a chemical to totally remove the thermal layer and now Im stuck with a non thermal lense until I get a replacement. Im gonna get one of the chrome colored lenses, they are sweet looking.
