Autocare Folding Sun Shade

As with the Halfords pair, these shades from Autocare come in a storage bag. Plus, they’re even easier to use as there is just one central sucker with a loop for easy removal. The two differ on their ability to cut out light – the Folding Sun Shade recorded one of the worst results, blacking out only about half as much light as the best. But it’s the cheapest buy here.
