Please review our sizing chart below to ensure the best fit for your UnderCool:

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.

Men's Sizing Guide:

Please note sizing is dependent on natural waist size not chest size.
ThermApparel recommends ordering a size smaller than your usual T-shirt size.
(If you wear a large T-shirt, a medium UnderCool will fit best.)
