I don't know how cold it is for the zero ratings. I live in semi-cold weather here in Texas, and I am impressed that I didn't need a coat when it became 28 degrees. I had on three shirts and these free country under my jeans, and I didn't feel the chill at all, nor was I wearing a coat getting in and out of my vehicle whilst shopping. I almost forgot I had them on; they clung to me so well. I chose xxl . I approve of these because, although I'd prefer 100% cotton, these days it's half cotton and something else, so i decided to give these a try.

Purchased for my husband. His waist is 38/40, inseam is 30. He has a bit of a belly. The XL fit perfectly. They aren't too tight or too loose. The waist is very comfortable. I will wash in cold water, hang to dry (to avoid static and over time wear to waist).

These are super warm and comfortable. My husband loves them!

Super thin, but so warm and form fitting. True to size.

Great and cozy. It’s true to size. I recommend.

True to size, very comfortable and help keeps you warm

These fit true to size and well made with reinforced waistband

I purchased these for a gift for a friend. They said these bottoms were very nice and comfortable. They are soft and kept him warm.

Great value, great quality, great packaging, great product, item described as posted, prompt delivery, great service, fits perfectly

They are not made of 100 percent cotton ,they don't keep anything warm ,I ride motorcycles all year long I expected 100 percent cotton , I won't buy them again ever
