Costa Del Mar Cook Sunglasses

Built for Explorers, Engineered for the Water
The Costa Cook is named after Captain James Cook, the epic explorer, navigator, and cartographer who mapped the world's most uncharted coastlines. Costa built these sunglasses for the same spirit: large, wide-fitting frames designed to handle every condition from flat harbor water to open-ocean swells. Lightweight, corrosion-resistant titanium construction means the Cook travels as hard as you do without adding bulk or fatiguing the nose and temples over a full day on the water.
Titanium Frame Construction
Titanium is the backbone of the Cook. The material is naturally corrosion-free, making it ideal for saltwater environments where lesser frame alloys pit, corrode, or warp over a single season. Beyond durability, titanium provides a strength-to-weight ratio that keeps the frame noticeably light on the face without sacrificing the structural rigidity needed to hold a precision optical lens in alignment. The temples flex rather than resist, so the fit conforms to your head rather than clamping it.
Hydrolite Temple Tips
Costa's Hydrolite rubber compound lines the temple tips and nose pads. Hydrolite is engineered to grip harder when wet, the opposite of most materials that loosen as sweat or water accumulates. That means the Cook stays locked in position whether you are paddling through a breaking set, fighting a fish, or simply sweating through a South Florida afternoon. The grip is secure without being stiff, and it does not degrade or become sticky over time the way standard rubber can.
Costa 580 Lens Technology: 580P vs 580G
All Cook lenses use Costa's 580 spectrum technology. The 580 number refers to the specific nanometer wavelength that Costa's lens filters block. By eliminating the High Energy Visible (HEV) light spike at 580nm, the lenses cut the most fatiguing, glare-producing portion of the spectrum while enhancing reds, greens, and blues. The result is sharper contrast and truer color on and off the water compared to standard polarized lenses.
The Cook is offered in two lens materials, each with distinct performance and optical characteristics:
| Feature | 580P (Polycarbonate) | 580G (Glass) |
|---|---|---|
| Lens Material | Polycarbonate plastic | Optical glass |
| Optical Clarity | Excellent | Superior (glass benchmark) |
| Weight | Lighter | Slightly heavier |
| Impact Resistance | Higher (polycarbonate flexes) | Moderate (glass is rigid) |
| Scratch Resistance | Good (hard coating applied) | Higher inherent hardness |
| Polarization | Yes | Yes |
| Prescription Ready | Yes | Yes |
Anglers and on-water users who prioritize optical precision often choose 580G. Those who want the lightest possible kit or plan to wear sunglasses in high-impact situations often prefer 580P.
Wide Fit and All-Day Wearability
The Cook is built on a wide frame fit. This is a deliberate design choice, not simply a large silhouette. Wide fit distributes weight across a broader bridge and temple span, reducing pressure points that cause headaches on extended wear. Combined with the lightweight titanium and Hydrolite retention, the Cook is one of the most capable full-day sunglasses Costa makes.
Prescription Ready
Both the 580P and 580G versions of the Cook accept prescription lenses. The titanium frame holds its shape precisely, which is a requirement for accurate prescription optics. Contact your optician or Costa's Rx service to explore prescription options with your selected lens material.

Frequently Asked Questions
- What is the difference between Costa 580P and 580G lenses?
- 580P lenses are made from polycarbonate plastic. They are lighter and more impact resistant, making them a strong choice for active water sports. 580G lenses are made from optical glass, which delivers the highest inherent scratch resistance and benchmark optical clarity. Both use Costa's 580 spectrum technology to block the 580nm HEV light spike and both are fully polarized.
- Are Costa Cook sunglasses polarized?
- Yes. All Costa Cook sunglasses come with polarized lenses. Costa's 580 polarization blocks horizontal glare reflected from water and wet surfaces and also filters the HEV light wavelength at 580nm for enhanced color contrast.
- Are Costa Cook sunglasses prescription ready?
- Yes. The Cook frame, in both the 580P and 580G versions, is prescription ready. The titanium frame maintains precise shape to support accurate prescription optics. Contact an optician or Costa's Rx program for options.
- Can you customize Costa sunglasses?
- Costa offers a customization program that lets you select frame and lens combinations. The Cook is also prescription ready if you need corrective optics. Visit Island Water Sports or call 954-427-4929 for guidance on the current Costa customization options.
- Do Costa sunglasses come with a case?
- Costa sunglasses typically include a protective case and a cleaning cloth. Confirm exact included accessories on your order confirmation, as packaging may vary by variant.
- Who owns Costa Del Mar sunglasses?
- Costa Del Mar is an American polarized sunglasses brand based in Daytona Beach, Florida. The brand has been part of the Luxottica Group (now EssilorLuxottica) since 2014 and continues to operate under the Costa Del Mar name.
- How do I care for titanium frame sunglasses?
- Rinse titanium frames with fresh water after saltwater or chlorine exposure, then dry with a clean microfiber cloth. Avoid leaving lenses face-down on hard surfaces. Store in the included case when not in use to protect the lens coating.
