Costa Women's Accessories

Frequently Asked Questions

• How do Costa's 580® polarized lenses improve on-water vision?

  Costa’s 580® polarized lenses cut surface glare and provide 100% UV protection while selectively filtering HEV blue light to boost contrast in reds, greens and blues—helpful for spotting baitfish and structure. The lens family includes glass and polycarbonate options and tints like Copper (about 12% light transmission) that perform well in variable or overcast conditions.
• Which Costa women's models fit narrow faces versus larger or oversized styles?

  For narrower faces, women’s-focused models like Waterwoman, Inlet and Anaa offer a snuger temple and frame profile, while medium-fit options include Loreto and Isabela (Loreto has an SFW of ~132). If you prefer oversized coverage, Cook and Brine provide larger lenses and a roomier fit (Cook: 60mm lens width, 52mm height, 15mm bridge). Choose the size that matches your face width and temple length, and account for Hydrolite® nose/temple grips for a secure feel on the water.
• What frame materials and construction features make Costa sunglasses durable for boating and fishing?

  Costa uses lightweight, corrosion-resistant materials like nylon and Beta Titanium for frames and integral hinges that stand up to saltwater exposure. Lenses come with scratch-resistant C-Wall coatings and repellent treatments, and Hydrolite® nose pads/temples shed water, oil and sweat to keep frames from slipping during active days on the water.
• How does the Waterwoman compare to the Cook for fishing and everyday wear?

  The Waterwoman is shaped and scaled for women with a narrower fit and feminine styling geared toward all-day comfort, while the Cook is an aviator-style unisex frame with oversized lenses and a double bridge for broader coverage. For sight fishing, Waterwoman gives a closer fit on smaller faces; Cook offers more peripheral coverage and a classic aviator aesthetic for those who prefer larger lenses.
• Which lens tint and coatings should I choose for sight fishing in changing light?

  A Copper tint with Costa’s 580® lens is a versatile choice for sight fishing because it increases contrast and works well in low to moderate light (Copper is around 12% transmission). Pair that tint with 580® glass for maximum clarity, C-Wall water/oil repellency and anti-scratch coatings; mirrored or polarized options can further reduce glare in bright conditions.
