River has taken the market by storm and is a disc with THE GLIDE. It's easy to throw and fits most player's power and skill levels. River is a fairway control driver and while it's not the fastest disc we have made and doesn't have the widest wing ever made, it is a disc for accurate driving and good control. With small fade and amazing glide, you can really let it fly on to those big anhyzer curves. About Opto: Opto is made out of some of the world’s most durable plastics.
