The spigen yellow bumper, two piece. I have the white iPhone 5. Since I like the bumper case, I just ordered a white one and another yellow for the wife. It feels nice and solid. However it does shift some when it is in the back pocket. I have full body ghost armour on the phone. I may take the side armour off and see if the rubber bumper material fits a little more snug.
