I have to admit that I always like iPhone cases like this. Granted, I was given the one for the iPhone 7 Plus, but you can see what I mean. It is transparent, which means you might not be able to see that there is even a case on your type of iPhone.
As for the name of Air Protect, it is so named because of the Air Protect Technology. It has some kind of air pockets on the side for some interesting protection on the sides of the phone, plus access to all the buttons.
The Belkin Air Protect SheerForce Case has a soft squishy feel to it, and I always like the feel of them. They are very durable as well.
You should be able to purchase the Air Protect SheerForce Case for the iPhone 7 Plus on the Belkin site for about $29.99.
