The Defender offers multiple layers of protection for your iPhone. The fit and finish are amazing. Apple would be hard pressed to do better. It has a soft lined, hard plastic inner case surrounded by a soft and flexible outer silicone case. Thankfully, the Defender comes with installation instructions.<br>The inner case has plastic tabs that hold the front and back halves together. It takes a few moments of pondering to figure out how to get it open, but it?s extremely secured once in place. It is not waterproof, so I highly recommend you stay away from the pool or hot tub with your phone in hand.<br><br><a href="http://www.pandamimi.com/otter-otterbox-defender-series-protective-case-triple-layeies-for-iphone-a-1583.html">http://www.pandamimi.com/otter-otterbox-defender-series-protective-case-triple-layeies-for-iphone-a-1583.html</a><br>
