Climax Fluorocarbon 0.35 mm Climax Freshwater Fluorocarbon Tippet Material is made from a material having the same light refraction as water. It virtually disappears in the water, making it impossible for the fish to detect! The hard, smooth surface of fluorocarbon creates less friction and heat on the material as you tighten your knot, therefore knots are stronger. 0.35 mm 7.7 kg 25 meter
