Looking a little like a Kevlar vest for iPhone, the new iFrogz Mix is a polycarbonate hybrid case with a thicker TPU edge. TPU (Thermoplastic polyurethane) is a choice material for it's resistance to abrasions, oil and grease, while retaining excellent elasticity. It's better than traditional rubber in some respects as it is lacking in overly adhesive properties (easier to pull out of the back pocket), with the added benefit of anti-microbial properties. Wow that sounded scientific... I need to stop researching and reviewing all these darn cases...
