I went skiing for my first time in 20 years a few weekends ago and never thought to buy something for my face.  It took 3 runs before it was frozen.  The ski shop at the mountain had this (although double the price) and boy am I glad I bought it.  It kept my face WARM the rest of the day.  I just got back from more skiing today and it continued to perform as I expected in even colder, single digit weather.

The only negative I've found is it does tend to fog your goggles more than they would if you weren't wearing it.  The trip a few weeks ago I just had a pair of sunglasses, and after buying this, I couldn't use the sunglasses any more because they were completely fogged.  Got proper goggles over the weekend and the fogging problem is mostly eliminated.

Fits great for my big head and I love the way it looks.
