Active Canis Reflective Shade Cover Medium, 3x3 m Silver canis that reflects at least 80% of solar rays. Which provides a much cooler environment. Keep in mind that: • Even if the silver screen reflects off the sun's rays and makes the environment cooler, it is not acceptable to leave an animal alone in the car on a hot day. • Keep in mind that some edges of the fabric may be a little hard, care should be taken when pulling the fabric over a fragile surface, e.g. car paint. • Never let the animal chew on the canis.
