"For Cygnett's WorkMate line of protective cases, ID'ers Shannon Brown and Haydn Smith have whipped up a tasty stew of thermoplastic polyurethane, silicone and deliciously rubberized polycarbonate. The combination was chosen to pack a lot of shock absorbency into a slim package while still providing a measure of ergonomics; the rubbery texture means it's less likely to fly out of your hand, but if it does, the protective design does the rest."
