I live in the upper peninsula of Michigan and I can not get enough of this sweater. It fits over my base layers, but is thin enough to go under a coat. It is also nice and toasty for chilly days. With a name like Patagonia you know it's going to be good for a while. If my opinion counts for anything I would highly recommend this product.
