River Opto Ice Orbit Floats in water It has the overstable characteristicsRiver is one of our most popular discs. And this thing has GLIDE. It is easy to throw and fits most players power and skill levels. River is a fairway control driver and while it is not the fastest disc we have made, and does not 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 those big anhyzer curves. DETAILED INFORMATION Diameter: 21. 5 cm Maximum
