444 Classic Sylk is the first modern line designed specifically for fine bamboo and rods. The "Sylk" replicates the fine diameter, long taper, supple feel, and subtle color of natural silk, but in a modern, easy to care for fly line. But, the "Sylk" isn"t just for bamboo! If you are one of the many anglers who have rediscovered the delights of fiberglass fly rods, this line is for you! It even works well on graphite for the finest presentations under the most demanding low water conditions. Can you say "midges?"
