Costa Aransas 580G Polarized Sunglasses
Named for the only town on Mustang Island where Spanish horses once ran free, the Aransas captures the spirit of barrier island life. A large acetate frame with a classic rectangular lens shape and refined design details, these polarized sunglasses carry the confidence of salt air and open water.
The Aransas belongs to Costa's Del Mar Collection and is built for men and women who want optical clarity on the water, behind the wheel, or anywhere the sun demands a serious lens. The 580G glass lens technology delivers Costa's highest-definition polarization, cutting glare while rendering color with exceptional contrast and sharpness.
580G Glass Lens Technology
Costa's 580G lenses are ground from pure glass for the clearest, most scratch-resistant optic in their lineup. The 580 filter blocks high-energy visible (HEV) blue light that scatters on water surfaces, sharpens contrast in harsh coastal light, and eliminates the washed-out view conventional polarized lenses produce. Whether you are fishing inshore, driving into a low sun, or spending a full day at the beach, 580G lenses make the visual difference immediately apparent.
Acetate Frame Construction
The Aransas frame is crafted from acetate, the material recognized for its color depth, lightweight feel, and comfortable long-term wear. Acetate is derived from cotton seed fibers and plasticizers, making it both flexible and durable. The material accepts high-luster finishes and rich visual layering that injected plastics cannot replicate. Regular hinges on the temples add to the frame's repairability and everyday reliability.
The frame features a single bridge and a full-rim design that holds the lens securely and maintains alignment through active use. The Costa C logo is engraved on the temple, a subtle marker of the brand's Florida-based heritage and commitment to sport optics.
Ready for the Water, the Road, and Beyond
The Aransas is rated for a wide range of conditions: fishing in salt and fresh water, everyday driving, fashion wear, and general sport use. It is also prescription-ready, so the frame can be fitted with corrective lenses by an authorized optical lab. Every pair ships with a cleaning cloth and a protective carrying case.
