This magnetic stretch-to-fit shade was designed to protect babies from harmful rays. Thanks to its innovative magnetic attachment system, it can attach to any metal door frame securely. As it attaches to the door frame, the window can be rolled down without removing the shade. The unique mesh fabric stretches in all directions allowing for maximum coverage. The size can be adjusted with the hook and hoop to gather excess fabric for smaller or slanted windows. The design blends seamlessly into any car interior while allowing fresh air on the ride and keeping your baby safe.
