Review on CUIMEI Fleece Neck Warmer Gaiter: Ultimate Windproof Face Mask for Skiing, Running & Cycling by Jermaine Chowdhury

I use them for running and mountain biking at around 35-45 and they work very well. They are really long which is good because you can put them on your nose and your neck is still covered. The material is very soft and comfortable, but thick enough to protect against cold and wind. I've only tested them at 35-45 degrees, I'd like something thicker if I go snowboarding or skiing. I also like that the material is stretchy enough to cover my nose but not so tight that it feels like my nose has been pinched.
