Stamp color may vary. Disc colors are assorted. The D Model OS is an overstable distance driver that is power player's dream. Those with more power can throw this disc hard, and it will work to fight out of its slight high-speed turn and finish with a harder fade, thanks to its fast, overstable flight. A good premium plastic is durable enough to stand the test of time and the elements while still providing excellent grip. We've hit all those marks with our DuraFlex blend that will continue to feel nice and grippy whether it's the first flight or long after the disc has slowly broken in.
