I prefer to use my iPad Air nude but am looking for a case solely for when I throw it in my carry-on backpack while traveling. I'm looking for something that is easy to remove for when I need to use and quick to put back on while not in use and getting thrown back in my carry-on backpack. I'm seeking something to protect against impact from books and other heavy objects. I know Otterbox makes great sturdy cases but it appears they take a long time to snap in and out of the case and are meant to be permanently left on. I'm currently using this: http://www.hardcandycases.com/device/ipads/ipad-2-3-4-cases/bubble-sleeve-for-ipad-1.html I like that I'm able to take the iPad in and out of the case quickly by just zipping it. Issue is the sides aren't that hard and I feel like the screen could easily be crushed. I'm thinking something similar but with metal instead of ballistic nylon. Something along the lines of this: http://www.pelicanprogear.com/produ...ardBack-Case-with-Liner/tablet-hardback-cases Thanks in advance for suggestions!
