anti-glare

[reps9]

Hi, I currently have the invisishield by zagg and like the screen protector; however, when I sit outside in the sun, the glare is horrible. I like the screen protector though and would like to keep it. Does anybody know of any easily removable/reusable accessory I can place over the screen while outside, but then take off once I'm inside? Any help would be greatly appreciated!

Thanks.
