The masks are simply THE BEST. We had few very cold days in Virginia and the temp went down to -5F with a wind chill of -15F and I was outdoors for 8 hours and the mask performed like a charm. I did not feel the wind or cold around the neck or face. I would highly recommend them. Actually I will be ordering a second set as backup just in-case Friendly Swede decides to discontinue them. Thank You Friendly Swede for an excellent product, and PLEASE DO NOT discontinue them.
