This product is crafted of our latest innovative fabric - Omni Shade™ Sun Deflector with UPF 50 sun protection. Those little sun-deflecting dots you see are specially designed to deflect sunlight away from the body so you feel cooler and stay protected. The dots reflect the sun's rays so well that the fabric will shimmer in any light. The stronger the light, the harder it’s working. And the soft, stretchy woven material feels amazing next to your skin while staying light and cool to the touch.
