Warm and comfy. These are thicker than typical long underwear, but much warmer as a result. Not so thick as to bunch up under a Tee shirt and long sleeve shirt. I like the color too. I would buy them again if I need another set.

Let me expand a bit about the warmth. Warm to me might not mean the same thing as warm to you. I like to cold and I like being out side in the cold. However, I do not like being cold. I really hope that made sense. I am not the type of person to "bundle" up in such a way as to limit my mobility. I like to hike and climb and run and be active in the cold, so I wear layers of thin clothing so I can be warm but mobile. Also it makes regulating my temp easier as I can take a thin layer off if I need too. I really like this set of long johns as my base layer in extreme cold. It's very thick and comfortable.

P.s. I live in New England. Last winter we had an average of 40" of unmelted snow for the entire winter season. It was a cold cold winter. And these preformed really well.
