The Costa Hammerhead, a Wide-Fit Favorite on the Water
The Costa Del Mar Hammerhead is one of the brand's most searched-for styles, and it earns that attention with a wide frame fit built to stay put through a day of fishing, boating, or beach time. It pairs that fit with Costa's polarized 580 lens technology, giving anglers and boaters the kind of glare-cutting clarity the brand is known for.
What's Built Into This Pair
The Hammerhead uses a polarized plastic 580 lens for cutting glare off the water, set in a wide frame fit designed for broader faces and a secure, all-day feel. It is also prescription ready, meaning it can be fitted with prescription lenses for anyone who needs corrective vision on the water.
Who Reaches for the Hammerhead
This is a go-to pair for anglers, boaters and anyone spending long hours on open water in South Florida, where glare off the surface can be brutal without real polarization. The wide fit also makes it a strong option for anyone who has found narrower sunglass frames uncomfortable or too tight around the temples.
How to Wear and Care for Them
Rinse the lenses and frame with fresh water after saltwater exposure to keep salt spray from building up on the polarized coating, and store them in a hard case when not in use to protect the lenses from scratches. Because they are prescription ready, anyone needing corrective lenses can have them fitted by an eyewear professional rather than choosing between vision correction and polarization.
Backed by Costa's Water-First Design
Costa Del Mar builds its entire lineup around one idea, enjoying life's greatest adventures while looking good and staying tough, and the brand is a dedicated maker of polarized sunglasses. That focus shows up directly in the Hammerhead's 580 lens and wide, secure fit.
Why Buy Them From Island Water Sports
