I bought this to replace an older baselayer top. I was really excited about the hood, because my beanie always falls off at night and I think the hood over the top will help it stay on. It fits really well and I think it will work for what I need. The only complaint I have is that the zipper seems a little short, and it's a little scratchy when it's unzipped. In the future I hope they make a hooded Alpine Onset top that has the criss-cross neckline like the Blackridge top, or upgrade the zipper backing.
