This tank top for men is perfect for daily wear or for working out. It's made of stretch cotton for a perfect fit and total comfort, plus it features built-in moderate compression to define your abs. Breathable mesh cutouts on the sides allow improved air flow to keep you feeling fresh all day long. The compression also offers back support and may improve your posture. Our special no roll-up technology was used to create the bottom of this shaper tank, keeping it in place.
