A really great helmet hood for its price. Used for commuting cycling from late autumn to spring with a normal cycling helmet and sled glasses and it doesn't get cold. At temperatures above 15 degrees below zero, a thin beanie-like scullcap is worn on top. The coldest period was about a week long, when it was 35-38 degrees below zero. The area around the chin is quite linty due to the contribution of the jacket collar and helmet strap, but if you think about the material this is and the number of uses on the back about 120 x 2, you can't complain. I think it's really cool.
