Under Armour Men's Heatgear Flyweight Singlet
The Under Armour Men's Heatgear Flyweight Singlet is made of the latest, lightest UA material — ideal for the technical runner. If being the lightest, most breathable fabric isn't enough for you, there are also mesh back and underarm panels for more ventilation. The Signature Moisture Transport System wicks sweat away from the body, anti-odor technology prevents the growth of odor causing microbes and smooth flatlock seams allow a full range of motion without chafing. In addition, graphics and logos provide 360° reflectivity for safer low-light runs.
