Great bang for the buck. It covers the front and the back of my neck well. I noticed that some people complained about it being to short. You just have to position it properly on your head so that you can pull it down more on the back of your neck.
Worked great snowmobiling in the mountains under full face Shoei helmet and under Scorpian half helmet on my motorcycle. Extremely cold conditions on snowmobile for six to eight hours at a time (with breaks) and in weather on the motorcycle in the 40's. This is a great product, very inexpensive for results. Others commented that the neck was to short but I had no such problem.
