The Costa Del Mar Ferg XL 9012 sunglasses honor the legacy of Costa founder Ray Ferguson in a larger, more inclusive fit. Named after the man who built Costa on a commitment to uncompromising performance, the Ferg XL delivers everything serious anglers and water enthusiasts demand: wider coverage, battle-tested durability, and Costa’s color-enhancing 580 polarized lens technology.
The Ferg XL is nearly 5% larger than the original Ferg, designed for those who need more frame or prefer greater facial coverage. The wide fit (142mm frame width, 61.8mm lens width, 48mm lens height) suits larger faces and provides an 8-base wrap that blocks light from every angle. Top hooding and integrated side shields deliver the kind of protection that matters when you’re staring into glare all day.
The pillow-shaped full-rim frame is constructed from Bio-Resin nylon—a durable, plant-based acetate that holds its shape in brutal heat, saltwater spray, and everything in between. Textured Hydrolite rubber is integrated into the adjustable nose pads and temple tips; it actually grips better when wet, so the frames stay put when you’re sweating or splashed.
Every pair ships with Costa’s 580 polarized lenses, available in both 580G (glass) and 580P (polycarbonate) across 19 frame and lens combinations. The 580 technology filters harmful high-energy visible (HEV) blue light at 580 nanometers, cuts harsh yellow wavelengths, and enhances reds, greens, and blues for superior contrast and definition. All lenses provide 100% UV protection and feature Costa’s C-Wall molecular coating for scratch resistance and easy cleaning—it repels water, oil, and sweat.
580G glass lenses deliver the absolute best optical clarity and are truly scratch-proof, plus they’re 20% thinner and 22% lighter than typical polarized glass. 580P polycarbonate lenses are lighter still, more impact-resistant, and about $50 less expensive, making them ideal for active use. Both options offer 99.9% polarization efficiency—the highest available.
The Ferg XL is prescription-ready, so you can add your Rx and keep the same 580 lens performance. The fully adjustable, vented nose pads let you dial in optical alignment and airflow to reduce fogging. Whether you’re sight-fishing the flats, running offshore, or just need serious sun protection with your prescription, the Ferg XL handles it.
This frame has earned its reputation among anglers who log long days on the water. It’s not about style points—it’s about seeing fish, cutting glare, and wearing sunglasses that don’t quit when conditions get tough.
