The FlexGrip features a two-tone silicone case with a smooth front as well as a textured, nubby rear surface which provides additional grip, making it perfect for those suffering from sweaty palms. Other features include a full-face screen protector (for the touch) and Click Wheel protectors (for the nano). As for the two-piece FlexScreen, you get a clear silicone case featuring the same textured back as the FlexGrip and a clear hard polycarbonate face shield. You won’t find all the relevant jacks blocked by either product, as Griffin are old hands at iPod accessories. Both will retail for $15 a piece.
