I'm not a big reviewer, but wanted to say somthing about this piece. I used it extensively ski touring in the PNW this last winter and spring and really loved it. I found it to be surprisingly warm, and would wear it by itself on sunny winter days, as long as it was not too windy. I did also wear it for sun protection on volcanos into the late spring, though a bit warm it still worked very well. Overall it is super comfortable and unobtrusive.
