Spine’s Air Skin cases for the iPhone 6 and iPhone 6 Plus are only 0.4mm thick and weigh only 4 grams and 6 grams, respectively. That’s hardly bulkier than a sticker skin, but the Air Skin cases are made using a new technology which compresses polycarbonate “to a stable form that can protect a device from bumps and scratches.” The case has a smooth matte finish and is coated with a layer of urethane to resist fingerprints and to prevent the colors from fading. The opening at the bottom of the case is big enough that you should be able to use most charging and audio cables with the case. The Air Skin cases are available in five translucent colors: soft clear, mint, gray, champagne, or azalea pink for $24.99 for the iPhone 6 and iPhone 6 Plus. Spigen requires an extended handling period of 7-10 days for these products.
