I have had three of these over the years and bought them when there is a discount, even out of season. The reason I like them is they are not at all bulky so easily go under clothes when it is very cold and a thermal needed. Due to my ineptitude I have put one in too hot a wash and it did go strange. But washed correctly they come up fine. Although they do not look as though they will be a warm layer they have been perfect for me and the roll neck which shows looks fine and not like a thermal vest.
