This tank top for men is perfect for daily wear or for working out. It's made of Supima cotton, which is one of the best cotton fabrics in the world. It's known for its soft feel and for being hypoallergenic. It has built-in stretch for a perfect fit and total comfort. It also features moderate compression to define your abs. Breathable mesh cutouts on the sides allow improved airflow 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.
