In 2014 we invented the Micro Thin Fly Line. Up to 20% thinner than comparable PVC fly lines & considered the most radical improvement in fly line design for over 30 years. Our micro diameter fly lines are compared to silk fly lines. We've taken our technology into the entire range of freshwater and saltwater fly lines. Sunray are defined by a system of low friction fly line coatings, low friction rod guides and low diameter fly lines. We build fly rods based on the principle of reducing friction, not increasing stiffness. We herald the return to softer rods and thinner lines.
