The River is an outstanding control driver from Latitude 64. Released in July 2010, this disc immediately received positive reviews from players for its high degree of accuracy and its outstanding drive. This disc is great as a fairway driver for tight upshots or a tailwind distance driver. Opto Air plastic has bubbles infused in the inner core of the plastic to bring the total weight down, while maintaining the durability and feel of Opto on the disc surface. Latitude has blown us away with this one... truly incredible engineering. Features: Lightweight Opto Air plastic Bubbles within the plastic take disc weight to new lows! Lightweight discs are easier to throw, glide farther, and are more friendly to the average thrower.
