I needed to replace some old style "waffle fabric long johns" and bought three different brands to pick the best one to buy. All three met my minimum standards, but Bodtek was the best. One thing I really appreciated was that the bottom's waist did not go halfway to my armpits. I HATE when they do that. Overall fit was soft, and snug. I bought the "small", knowing they would be extra snug. Just the way I like them.
