My only vehicle (at the moment) is a Harley Davidson. Ever dreamed of finding that old pair of jeans or your favorite shirt to wear when the weather just got colder? It's not winter yet, but thank god the heat is going. It's the same jacket. I put it on and it instantly became like an old favorite. I ordered a size up and I'm glad I did. There's plenty of room for your beloved T-shirt and lightness underneath. Flannel shirt with fleece inside. I'm taking one for my young daughter's Christmas present and the other for my shift. I really liked this product!
