Coldwater Clouser™ Fly Line  Casting heavy or wind-resistant flies has always been a challenge, even for good casters. Jim Vincent and Simon Gawesworth collaborated with Bob Clouser in developing the Clouser line. Bob is the famed fly tier, guide, instructor and conservationist best known for inventing the Clouser Minnow, one of the most versatile flies for both fresh and saltwater. The Clouser line, with its unique reverse compound taper and a bullet front taper, turns over heavy flies into the wind without effort and smoothly transfers energy to prevent the characteristic “kick” with heavily weighted flies. The Clouser line includes the RIO proprietary welded loop on the tip for quick leader changes.
