iPhone 6 Bumper Case with Rubber Grip?

The original iPhone bumpers had a nice rubber grip, so it wouldn't slide out of your hands. Unfortunately, Apple no longer makes them for iPhone 6 and the only 3rd party one I've tried from Poetic is made with a hard rubber, that feels like plastic and slides very easily out of my hands. Does anyone have a better recommendation for a bumper style case with a nice rubber grip that stays in place while in use?
