I have had this base layer/jacket for about 3 years now. I wear it under my jacket every time it gets below 10 degrees. This base layer/jacket is incredibly warm as well as soft. It's made out of 100% polyester so it wicks moisture very well. The design is very clean, it has a fleece-like material running through the outside of the center and the whole inside is made of that same fleece material. It has three pockets, one on the chest and two lower pockets. Overall, I think this base layer/jacket is a great layering piece to have on some of the coldest days of the season!
