The Mizuno Lady Drylite Singlet Running Vest is engineered with DryLite. This high-performance technology helps to draw sweat away from the body so that it evaporates into the air from the fabric surface to provide maximum comfort whilst you exercise. BlindStitch seams lessen bulk and reduce the risk of irritation that can occur from repeated rubbing over seams. Reflective detailing on the front and back of the t-shirt ensures you remain seen in low light conditions, improving your safety.
