The Kiddopotamus Ray Shade shields your child from over 99% of UVA and UVB rays. Because one bad sunburn as a child doubles the chances of developing skin cancer later in life, pediatricians recommend the RayShade. The RayShade has been tested and rated at 50+ UPF (Ultraviolet Protection Factor). The RayShade's soft, tightly-woven nylon/lycra meets the highest possible rating for sun protection, so your child is safe and sheltered anywhere on-the-go. Easily-adjustable, the RayShade extends the protective shaded area under every stroller canopy. Place over any canopied stroller, jogger or pram with the front curve of the hoop facing forward. As the angle of the sun changes, you can quickly adjust the RayShade forward or back to provide your child with the right amount of sun protection.
