Ever since the very first iPod, there has always been an interest for some people to find the most see thru protection so they can proudly display their beloved gadget while protecting it from being scoffed up. That said, the Griffin FlexGrip is probably something ideal for those looking for see-thru protection on the iPhone 4.
The FlexGrip is made of a rubbery-flexible material known as TPU entirely. There are two finishes and the one I have is the clear version; while it is not completely see-thru, this translucent case will display the back of your iPhone 4 clearly when installed and pressed up against the iPhone. Installing FlexGrip on an iPhone 4 takes seconds and the fit is nice and snug. When installed, it barely adds any thickness to the device.
I like the FlexGrip because it offers a clean finish and keeps the iPhone 4 to a minimalist style. The fact that the entire case is made of TPU which offers added grip traction which is always a good thing. At $19.99 MSRP, this is one of the better valued iPhone 4 cases on the market today.
