Scientific Anglers Sharkskin technology is a precise texturing process that embosses the surface of the Scientific Anglers Sharkskin Fly Line coating with a repeating geometric micro-pattern. The finished surface is no longer smooth, no longer exhibits unwanted line flash, and can be optimized via the engineered shape, depth, and frequency of the pattern to yield greatly improved line-to-water floatation, casting performance, and overall line suppleness and durability.
