The Costa Finlet sunglasses are built for anglers and outdoor explorers who need dependable performance in the toughest environments. Engineered for durability, protection, and all-day functionality, Finlet combines rugged construction with modern design features made specifically for life on and around the water.
Designed with an 8-base wrap, Costa Finlet sunglasses provide enhanced coverage from sun, wind, glare, and harsh outdoor conditions. Finlet-inspired side shields add an extra layer of protection by reducing peripheral light intrusion and helping maintain clear vision in bright marine environments. Whether fishing offshore, navigating open water, or exploring rugged coastlines, Finlet delivers the coverage serious watermen demand.
Retainer-ready temple tips allow users to attach their preferred eyewear retainer for added security during boating, fishing, paddling, and other active adventures. The secure fit helps prevent accidental loss while moving through challenging conditions on the water.
Built to withstand long-term exposure to saltwater and extreme outdoor elements, Finlet features double-injected Hydrolite® technology that improves grip, comfort, and durability while preventing delamination over time. This advanced construction ensures a long-lasting, high-performance frame that remains reliable through demanding use.
Combined with Costa's premium polarized lens technology, Finlet sunglasses reduce glare, improve visual clarity, and enhance visibility in bright outdoor settings. Durable, performance-driven, and adventure-ready, Costa Finlet sunglasses are designed to help watermen stay focused and protected wherever the journey leads.
