The Safety 1st Rear SunShade blocks the sun's harmful rays from hitting a rear-facing infant without distracting a parent's view of the road. The unique frame material is self rolling, with no winding shade mechanism. Free of adhesive residue, the suction cup mounting is easy to place and remove at any time, and its universal size, 33"L x 13"H, will accommodate most rear car windows. The collapsible, compact design makes it easy to store and perfect for travel. A "Baby on Board!" graphic lets other drivers know there's a little one in the car. To clean, wipe it with a dampened cloth and towel dry. Weight: 4.6 oz.
