I purchased both the 2 layer and single layer long sleeve T Shirts. Excellent shirt, warm, great quality not to mention it arrived quickly. We have the new front load Samsung washer and dryer and the shirt did experience some shrinkage in the body. Most reviews said no shrinkage, but it is cotton and did shrink some. It is oversized so it is fine, but if you are a big guy who borders large to extra large, you might want to get the extra large. Sleeve length was fine. I recommend, but again mine did shrink.
When I purchased the first one I found it so comfortable that I had to order more. They are very warm and just perfect for wearing under a light jacket.
I bought one of these for a grandson a few years ago. They live in TN and it loves it...says it is really warm. I have bought some more this year. He also loves the Ragg hat. I will buy one for my son also
