Muscle Tank made with ATB-UV+ Silver® antibacterial technology, a proprietary fabric blend with the element silver embedded in its fibers, utilizes the odor fighting properties of silver. Silver releases positive ions that attach to the negative ions of bacteria, which prevents the growth of the bacteria. This unique fabric structure also enhances sweat wicking and quick-dry dispersion, helping regulate body temperature and keeping you odor-free during and after training sessions. Designed with an Extended Scallop Hem to negate shirt ride up when bending, squatting or jumping. Constructed from our SilverPlus® Fabric.
