Cortland Liquid Crystal Tarpon Taper with PE+ Coating, Cortland’s tournament-winning Liquid Crystal floating fly lines represent a glimpse into the future of floating fly line technology. Made by extruding a proprietary blend of clear polyethylene and advanced co-polymers over a monofilament core. The hard PE+ coating has a super-smooth finish with an exceptionally low coefficient of friction so it shoots faster and farther than any conventional PVC floating line ever made. The coating is permanently fused to the core so there is minimal line stretch — for unequaled strike detection and hook sets. The clear line is virtually invisible in the water, while the sky blue offers a line that's nearly invisible to the fish, but easily seen by anglers and their guides.
