Review on Versatile Winter Outdoor Windproof Neoprene Thermal Half Face Mask - Ideal for Snowboard, Ski, Motorcycle, Cycling, Hiking & More by David Maxwell

A couple of points: if you wear glasses with them they will fog up and I thought "breathability" should eliminate that problem. Does not fit tight around ears or neck. I thought it would fit tighter and maybe I was wrong, but it also means the item didn't meet my expectations. Even though the round part is supposed to let air in or out, it doesn't seem to do that either. It's more about the optics. Poorly processed optics. the inside is warm and quite nice with a scarf.
