I wore these all winter. So comfy and warm, a great buy.

Really love the comfort of these. They are very form fitting. The only issue is, the bottoms are for someone with a 41" inseam. I usually wear 32x34 pants and, as you can see from the pic, these are a bit long. I suppose it's extra material for your upper body but I don't really want that. I wish they would separate them so one could order the top and bottom separately. Other than the sizing, they are the warmest, most comfortable thermals I have ever worn. Other than the silly length, I'm happy with my purchase. Probably going to order another set in extra small and see if those bottoms would fit. I'm 6'0" 170 lbs

Thermajohn Long Johns Thermal Underwear is a great way to stay warm in cold weather. It's made of a soft, comfortable fabric that is also very warm.

The long johns are made of a blend of polyester and wool, which makes them both warm and breathable. They also have a snug fit that helps to trap heat.

5'9 172 lbs, swimmers build: Medium fit good with spare length. It's polyester and spandex not fleece. It feels comfortable and thicker with air getting through. I say it's good for 50 degree weather and below. Otherwise, your sweating.

Thickness was just what I was looking for it was on point.
