Built for anglers and outdoor enthusiasts who demand lightweight comfort and dependable performance, the Costa Del Mar Fly Line Polarized Sunglasses in Matte Black feature Gold Mirror 580P polarized polycarbonate lenses engineered to reduce glare and enhance visibility on and around the water. Inspired by the precision of fly fishing, the Fly Line delivers a clean, modern design with Costa’s legendary optical technology for all-day adventures.
The Costa 580P polarized polycarbonate lenses enhance color and contrast while filtering harsh yellow light and reducing glare from reflective surfaces. Lightweight and impact-resistant, the Gold Mirror lens features a copper base tint that improves depth perception and contrast, making it an excellent choice for inshore fishing, freshwater streams, flats fishing, hiking, and variable to bright light conditions.
The durable Matte Black bio-resin frame offers lightweight comfort and long-lasting durability for active lifestyles. Hydrolite® rubber nose pads and temple tips provide a secure, non-slip fit even in wet conditions, while the wraparound design helps block peripheral light for improved visibility. With 100% UV protection, the Fly Line keeps your eyes protected whether you're casting on the river, boating, or enjoying everyday outdoor activities.
From technical fly fishing to weekend adventures, the Costa Del Mar Fly Line delivers the premium optics, lightweight performance, and rugged reliability trusted by serious outdoorsmen. Shop authentic Costa polarized sunglasses at Simpson Outfitters for premium fishing and outdoor eyewear.
