COSTA Fly Line Polarized Sunglasses

Fly Line is engineered for serious watermen who demand performance without compromise. Built on the proven fit of our Reefton frame, it delivers an 8-base wrap for superior coverage and protection in harsh conditions.

Double-injected Hydrolite on the nose and temple tips ensures comfort and secure retention so you stay focused on the water. Retainer-ready temple tips let you attach any retainer of your choice to keep your frames secure. Costa 580® lenses cut through the noise. Designed by our in-house light spectrum experts, they absorb harmful high-energy blue light, enhance reds and greens for clarity, and filter harsh yellow to reveal true water conditions. Where standard lenses fall short, Costa 580® delivers the contrast and color definition serious anglers need.
