What Our Gearhead® Experts Are Saying:"If you're serious about visual clarity, the 580G lenses in the Rincon II are next level. I wear these for long days on the boat, and the glass lenses give me unmatched sharpness without distortion—even after hours in bright light."When you're chasing fish at sunrise or navigating open water under midday glare, you need eyewear that performs with precision. The Rincon II 580G Polarized Sunglasses bring Costa’s legendary heritage into a new era of adventure, upgrading their classic Rincon silhouette with enhanced coverage, sweat-ready engineering, and the unbeatable clarity of polarized glass lenses. The 580G lenses are crafted from lightwave glass—20% thinner and 22% lighter than traditional polarized glass—delivering the best clarity in the game with long-term scratch resistance. They sharpen contrast, block out harmful high-energy blue light, and filter harsh yellow tones, helping you see detail even in blinding sun or on reflective water. With added micro side shields, hooded design, vented nose pads, and anti-slip temple grips, the Rincon II is built to stay secure and clear through everything from offshore fishing missions to beachside treks.
