Warm & comfy.
This thermal set is very comfortable under my clothes. Doesn't make me feel over dressed.

Slim, comfortable, and warm too.
I was looking for a new affordable thermal underwear for my son this winter. This is a two piece set that is very comfortable and keeps warm. The outside material is like a poly microfiber stretchy material lined with a thin fleece microfiber material. (That's the best I can describe today's high-tech materials). My main concern was that it's thin enough not to bulk up or be tight under his normal clothing. Being that he works all day, he can't feel stiff or uncomfortable. Overall, excellent pair. Well priced and arrived quickly.

Super soft under layer but strange small sizing
The son I purchased this for is 5'7" and athletically built, and usually a men's size small. I ordered a size up after reading that it runs small. The medium bottoms were fitted but fine, however the top was too narrow across the chest and the seams were too tight at the armpits. My younger son has a very narrow build, so it was loose enough on him, but the sleeves were a bit short. I will be returning it. Great material, but the sizing needs to be adjusted to a more universal fit.
