I bought this last winter during a very rare cold spell here in Alabama. Morning temps easily in the single digits. Working outside most days, I needed a better way to keep my face warm while not being too bulky so I could still wear my hardhat. I bought this to try, thinking that I would have to layer it because there was no way this thin fabric would keep me warm. Oh how I was wrong! It kept me warm in single digit temps and even kept most of the wind from getting through which was amazing to me. I liked it so much, I bought another to take hunting with me. Great Carhartt product and very much worth the money.
The Carhartt helmet-liner mask is a great purchase. It combines head warmth, and the face and neck protection you would get from a gaiter. It's comfortable under a hard hat and easy to pull right up over your nose as soon as that wind starts blowin'. After switching positions a few times, the neck gaiter starts creeping up and letting some wind in, but hey, put down the tools and reposition it. Also, when those temperatures really start to drop, some type of knit hat will also be needed. The only downfall here is that it is impossible to wear it over your nose without fogging up your safety glasses!
i purchased this product to wear when riding my 4wheeler. and let me tell you it works like a dream. keeps my ears warm and can cover my nose and mouth any time. also it not to thick so you can breath.
I do traffic control (flagging) for work. I had lost my US ARMY ECWS base hood and bought this to replace it. In the end it actually fits better, is more comfortable and is better stitched than the USGI ECWS hood is. I have seen days ranging from 28° to 40° and it has kept me warm and the wind off my face and the back of my neck. Another plus is it isn't too bulky under a hard hat.
I would recommend it to anyone who is out in cold weather for work or play
