A very special prophylactic to waterproof your phone

While unfortunately unable to prevent unwanted pregnancy texts, Smartskin Smartphone Condoms are packs of three (reusable) wallet-stashable stretchy thermoplastic sheaths that can slip onto and seal out liquid from your mobile at a moment's notice, i.e., getting on a boat, riding your bike in the rain, accosted by a Super Soaker-wielding gang of children, etc. And, they're also supposedly "excellent if you suffer from a particularly sweaty groin", so... yay!
