RIO’s JUNGLE SERIES of fly lines are designed to withstand the heat of tropical and jungle destinations. Each line is built on RIO’s low-memory DirectCore that is extremely easy to anneal (stretch) and lies perfectly straight on the water, yet retains the stiffness needed to cast in hot conditions. Each line has a short, quick-loading head that will easily cast and turnover typical large flies, and a range of density options ensures anglers are covered for all species, conditions and waters.
The F/S3 line is a floating line with a 20ft long, type 3 (3-4 ips) slow sinking tip.
