Omni-FREEZE ZERO is sweat-activated cooling. The blue rings on the interior act as a cooling agent. As you perspire, they kick in to not only cool you off but also accelerate the wicking process. On top of that, you also get UPF 50 to protect your skin from harmful sun rays. It's the classic lightweight performance Shirt that keeps you cool, with ZERO tolerance for overheating.
