with the latest iPhone (along with iPod touch and nano), Apple kind of firmed up their affinity with aluminum. and as such, as end users, adding yet another piece or two of aluminum to protect your iPhone seems like a logical move. speaking of aluminum protective case, designer Andrea Ponti has conceived something that goes inline with Apple’s aluminum design mantra. the case, known as Ag++ Metal Bumper for iPhone 5, is crafted from aircraft-grade aluminum and it stands out from the rest of the bumper out there with its ergonomic design that allows for a firmer grip of your iPhone 5. it comes as a two-piece design and both parts are locked together with hex screws, which adds to the industrial look and feel. the kit comes standard with carbon fiber pattern skin back plate in either silver or black, which you can of course choose not to utilize but judging from the iPhone 5 susceptibility to scratch, we thought it might be a good idea to install the said back plate. if you choose protection over thickness and bulk without sacrificing the dope look, the Ag++ Metal Bumper for iPhone 5 is the protection of choice for your precious 5. available via Pineway Asia for $49.99 a pop. take a few more (closer) look at this awesome bumper case for iPhone 5 in the small gallery below.
