The material and tight fitting helps keep you warm…
Size: Large, Color: Green
I am 5’8” tall and weigh in at 172 lbs dressed. These are the most comfortable cold weather shirts I have ever worn. In my humble opinion, what makes these shirts so comfortable and warm is the tight fitting and the soft, fleece like feeling on my skin. I wear and ordered the large size. The shirt is cut so they fit close to one’s body and look great compared to other brands of shirts that end up looking like one is wearing a potato bag. The tight fitting helps keep me feeling warm. No cold air pockets.

Better than expected
Size: X-Large, Color: Light Red
Intended to use it as an everyday shirt but the quality we much better than expected for the price so it's now a more special occasion pullover. Nice soft and comfortable material, well constructed and sewn, good loose but not baggy fit, nice heft and substance around the collar. Lightweight but not thin fabric. Excellent value = 5+ stars

Beware of Size
Size: XX-Large, Color: White
Inconsistency in size per other reviews. The site said XL was my suggested size.....I usually follow that advice. I went XXL this time and happy I did. The neck is a medium and the rest is maybe XL....it feels "fitted" too...not very loose. I will keep it as I like a snug neck---but this needs effort to pull over my head. Having said that, the material is soft and not too thick. Just beware of sizes.
