iPad Air Smart Cover

If you're not too worried about scratching the back of your iPad Air, or if you've already got a case that covers the back but not the front, then Apple's iPad Air 2 Smart Cover might be ideal.
You can no longer buy it directly from Apple but we have spotted it available at Amazon for around £64, and as low as $49.99 if you're visiting from the US. The Smart Cover automatically wakes up your iPad when you lift the front flap, which is where the 'Smart' part comes in.
If you've got an original iPad Air, we have a guide to the best cases for that too.
