I love 2UNDR. Have you ever felt like you were wearing a second pair of skin that moved seemelessly around your body?  Because that's what 2UNDR is like, firm but comfortable compression against your body without any of the material pinching or snagging on your body. I use these to workout, play golf, wear on formal occasions or just lounge around the house. You'll feel slimmer and your pants will fit more true to size without all of the excess material bunching up underneath you. If you aren't buying these, I feel sorry for you.
