Used my Jacket for the first time in the snow on the moors last week. Proved highly efficient in keeping out the wind though am yet to try it in wet conditions. Over heated slightly on gradual long climb, though probably more due to me being used to wearing more layers with previous jackets in similar conditions. Just one minor point is that when the zip is full up above the chin, there is still quite a gap between the jacket and face, even with the hood fully tightened which can lead to a cold chin in windy conditions. Wearing a bandana or similar would help here in more extreme weather. Extremely light, fits well and smart. Will prove to be a valuable asset for winter hiking on the hills. 4.5 Stars
