Airflo Sightfree G3 is a 3rd generation, low diameter fluorocarbon that offers incredible breaking strain to diameter ratios. Made from 100% fluorocarbon, Airflo Sightfree G3 has the same refractive index & low visibility as regular Sightfree, but with a lower diameter for a given breaking strain. Low refractive index almost invisible in water High specific gravity cuts the surface like a knife Greater abrasion resistance for longer durability Increased knot strength reduces dropper bust-ups 100m Spools
