*Waist Measurement: If you bend to the side, you will crease in the middle of your body; this is your natural waist. That's where you want to take your waist measurement.

*Sizing Guide: ThermApparel recommends ordering a size smaller than your usual T-shirt size. (If wear a large T-shirt, a Medium UnderCool will fit best.)
