I got it for my husband who loves to wear underpants in the winter. It is very thin yet keeps him warm. He loved it when he tried on. He is 6'2" weighs 175lbs. Medium is perfect size. It is tight enough and with front open similar to underwear, it would be ok to wear it alone without underwear.

My husband loved these. They are soft and stretchy. Very comfortable to wear under his work clothes. He also likes to use them as pajama pants. Waist band didn’t bother him. They are thin but kept him warm. Will be buying him more for the winter. Also I will be buying him the long sleeve shirts.

These are great for every day wear during the winter if you're cold natured like me. They're light enough that you can wear them under work attire. Not too hot indoors and make a difference dealing with cold, windy conditions going in and out of work, shopping or doing yard work. Granted they're not marino wool, but you can get them for a fraction of the cost.

I love the fact that the pants are thin, but they are also very warm. Many times, we end up with thick, sweaty long underwear and it gets worn one time. These stay up, dont sag, and keep me warm without the feeling of a swamp!

Soft, smooth, stretchy great compared to rival sports brands as they are not super tight. Can be worn around the house or on a run/to the gym. If it was colder outside I would also consider using these as a second layer of warmth for my legs!

Very comfortable and lightweight. Very effective protection against the cold. Not bulky and will not hinder movement.

Excellent for cold weather athletic performance (sking, etc). Kept dry and comfortable even though I started to sweat.

Really Comfortable and Keeps You Warm

Great fit and warmth from these light weight base layer pants.

They wisk away perspiration and maintain warm all in one. I want to try these out under shorts as a transition between shorts to sweats when running. My only concern is if they shrink during washing.
