I bought this unit 6 years ago and just bought another one. This is a good shirt for those winter days when you get home and can't warm up. It's lightweight but gives you extra warmth and didn't restrict movement before. I still have my old shirt and am wearing it over this one. The sleeves are shorter, which I like. However, this is a much slimmer fit. When you're indoors you want to be comfortable and if they don't loosen up after wearing them I'll probably just toss them in a drawer and never see them again.
