Discraft says, "Boasting impressive torque resistance and an assertive fade, the Zone OS has earned its stripes as a PDGA certified beefcake. Whether you need a disc for forehand throws, spike hyzers, or approach shots, this disc can handle it all even in the toughest of winds and terrain."
This run of Zone OS is in the Jawbreaker plastic which is a stiff and grippy plastic with a jawbreaker like swirl effect.
