I tried a little test with my Ag Gear hoodie in January, working out in the cold, wind, snow...in weather that called for a jacket...but I went with only the hoodie. It kept me warm, was not tight (had "room to work" in the chest/shoulders, etc.). This hoodie is just as good quality as my Carhartt and Ariat hoodies. However, where this hoodie stands out is around the waist. It has a "hip hugging" design that keeps the hoodie from riding up, or billowing so as to let the cold in. So glad I ordered this item. :)
