I ordered this sweater for my husband without reading the reviews. I was expecting an average weight and when I felt the packaging I figured it was just a nightie or pajama by weight. It's very, very easy. I figured it would be similar to other zip codes I've gotten from a shop or exchange at the base. It still fits perfectly and is actually just what he needs on a construction site to get in and out of his office. He can put on a thermal shirt or shirt. It's thin enough to wear under a winter coat when it gets really cold on the North Carolina coast.
