Shade of disc color may vary. For example, yellow can be a mustard yellow or a bright yellow.
River is one of our most popular discs of the past decade, probably due to its tremendous GLIDE. The River is a fairway driver for those accuracy shots that demands good control. It is easy to throw and fits most player's power and skill levels. With small fade and amazing glide, you can really let it fly on those big anhyzer curves.

About Opto Air: Opto Air uses the same material as our durable Opto Line plastic. It is modified and the runs are done in a different way to achieve a stunning result of lighter weight discs that still has a layer of solid plastic at the tip and bottom of the rim to protect the alternated material that is mostly centered in the middle of the rim but also spread out slightly over the top of the discs to keep the weight distribution as close as possible to the Opto and Gold Line discs.
