Function is an easy to throw fairway driver that offers the most understable flight path of any Discmania disc produced to date. Those that enjoy the performance of the Essence but seek something just a bit flipper for their game are going to fall in love with this one right away. The Function is engineered for players with lower level arm speeds, beginners/amateurs, and those that enjoy the flight of an understandable fairway driver that executes turning shots quickly and easily. Neo - Semi-translucent, premium plastic. Not only great looking but also the most durable and rigid Evolution line plastic! Still has some flex to it, and thanks to the special finish it offers an awesome grip.
