Spigen Air Skin is the thinnest in the Spigen family! AirSkin was crafted for the true minimalist in mind. The secret to its extremely thin and lightweight capability is that it is made of polypropylene. AirSkin has a frost finish that helps with better grip and fingerprint-resistance but best of all, measures only 0.36mm in thickness! AirSkin is so thin that it leaves your phone barely noticeable, make your phone feel as if it never had a case on!
