Our new ESN was designed specifically for European style nymphing techniques developed to maximize catch rates. Built with a KonneticHD backbone, the ESN allows anglers to experience unmatched blank recovery, increased sensitivity, reduced weight-in-hand, and superior shock absorption to better hold fish. The refined medium action has been designed with a variety of long and short line techniques and situations in mind, allowing you to confidently work any stretch of river. From small creeks to big rivers, the ESN is as dynamic as the water.
