4 stars instead of 5 only because I am a woman writing about a man's shirt and don't know how to recommend the shirt to men. I LOVE these shirts for my use and have ordered several over 2 years. I wash and dry them ruthlessly, against the washing instructions. Consequently, they shrink and ruffle at the bottom which doesn't bother me at all because I plan for these results. In the meantime, I get soft, warm, comfortable shirts to wear throughout the winter, either during the day OR to sleep in at night. If men tuck in these shirts, the slight ruffling shouldn't be a problem.
I just bought another one of these, my first double layer one I got as a gift 3 years ago and love it, feels good and keeps you warm, great underlayer. It's a must pack item when I travel for work around the country, and I also bring it ice fishing been in temps -25 with this on and stayed dry while being active
Overall this shirt is well made and comfortable, however no matter how to dry this shirt after washing it will require ironing to eliminate the "just slept in" look.
