Show off your style when the competition heats up with the Saysky Men's Reactive Flow Singlet. This soft, ventilated singlet enhances breathability and features a racerback design that allows for unrestricted arm movement as you tackle miles. Its ultra-lightweight fabric provides a next-to-skin feel while improving sweat evaporation. Run in the rain with confidence, thanks to a special waterproof treatment. As a unique touch, a water-reactive print appears when the singlet gets wet from sweat, rain, or moisture and disappears when dry.

Follow recommended care instructions will help maintain the effect and extend the lifespan of the print, which will gradually fade over approximately 30 washes.
