Latitude 64 Opto River

The River sets the standard for High Glide discs — particularly known for it’s long, straight, floating finishes, even when thrown with less than full power.

The River’s overstable high-speed flight adds excellent control, helping ensure those long finishes travel in exactly the direction you intended.

Manufacturer’s Description

“River is one of our most popular discs. And this thing has GLIDE. It is easy to throw and fits most player’s 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.” Source
