The Costa Del Mar Brine 9017 Sunglasses deliver serious fishing performance in a frame built for smaller faces. Designed with a narrow fit and 59mm lenses, the Brine wraps comfortably around your head without the gaps or pressure points that plague anglers with more compact features. If you've struggled to find polarized sunglasses that actually stay put when you're working a rod, these are worth a look.
Costa 580 Lens Technology: Glass vs. Polycarbonate
The Brine is available with Costa's 580G glass lenses or 580P polycarbonate lenses—both filter harmful light at 580 nanometers to boost reds, greens, and blues while cutting haze. The difference comes down to clarity versus weight. Glass (580G) offers superior optical clarity and near-scratch-proof durability, making it ideal for saltwater anglers who need to wipe salt spray off their lenses throughout the day. Polycarbonate (580P) is lighter and more impact-resistant, plus it costs about $50 less. Both provide 100% UV protection and 100% polarization with Costa's C-Wall coating to repel water, oil, and sweat.
Choose your lens color based on conditions: copper for inshore sight-fishing and variable light, green mirror for offshore brightness, blue mirror for open water glare, and gray for true-color perception on long days. All lenses are prescription-ready, so you can add your Rx and skip the clip-ons.
Hydrolite Grip and Ventilation
The Brine's co-injected frame pairs durable nylon with Hydrolite rubber on the temples and nose pads. Hydrolite absorbs moisture instead of getting slippery, so the frames lock in place when you're sweating or wet—a real advantage when you're leaning over the gunwale or hiking in full sun. Integral vents on the frame increase airflow and reduce fogging, a detail that matters more than you'd think during humid mornings on the water.
The frame measures 59mm lens width, 18mm bridge, and 130mm temples. Costa lists this as a "narrow" fit with a high bridge design, meaning it works well if your nose bridge sits above your pupils or if standard wrap sunglasses leave gaps at the top and bottom. The 8-base curve provides solid side coverage without the tunnel vision some heavily wrapped frames create.
These are fishing sunglasses first—minimal styling, maximum function. The Brine has been a staple in Costa's lineup for years, and it's earned a reputation among anglers who need a smaller frame that doesn't compromise on lens quality or durability. Prescription-ready, built to handle saltwater, and light enough to forget you're wearing them.

Comfortable & polarized. What else could you want?
These glasses are fake! Don’t let the $20 “discount” fool you. Also, took 3 weeks to get here. Don't let the "ship next day" banner at the top of the website get you either! Would NOT recommend this lousy company to anyone.

Frequently Asked Questions
Are Costa Brine sunglasses good for small faces?
Yes, the Costa Brine 9017 is specifically designed with a narrow fit for smaller faces. With a 59mm lens width and 18mm bridge, it's built for those who prefer less coverage or have a slightly narrow head. The high bridge fit works well if your nose bridge sits above your pupils, and the wrap design prevents gaps without pressure points that larger frames create on compact faces.
What's the difference between Costa 580G and 580P lenses?
The 580G lenses are made of glass and offer superior optical clarity and scratch resistance, making them ideal for saltwater use where you need to wipe lenses frequently. The 580P lenses are polycarbonate—lighter, more impact-resistant, and about $50 less expensive. Both provide 100% UV protection, 100% polarization, and Costa's 580 technology that filters yellow light at 580nm to enhance color and contrast.
Can I get prescription lenses in Costa Brine sunglasses?
Yes, the Costa Brine 9017 is prescription-ready and can accommodate most prescriptions. Prescription ranges typically support SPH and CYL combined from +3.00 to -5.00, with cylinder not exceeding -3.00. You can order them with prescription 580G glass or 580P polycarbonate lenses in your choice of lens color and mirror finish.
What lens color is best for fishing in the Costa Brine?
Copper lenses are excellent for inshore fishing and variable light conditions, enhancing contrast for sight-fishing. Green mirror lenses work well for offshore and bright conditions, while blue mirror is ideal for open water and maximum glare reduction. Gray lenses provide true color perception and are versatile for all-day wear. All Costa 580 lenses filter yellow light and enhance reds, greens, and blues for better water penetration.
Do Costa Brine sunglasses stay on when wet?
Yes, the Brine features Hydrolite rubber on the temples and nose pads that actually grips better when wet or sweaty. This co-injected material absorbs moisture instead of becoming slippery, keeping the frames secure during active fishing, boating, or water sports. The frames also include integral vents to reduce fogging and improve airflow.
How do Costa Brine sunglasses compare to the Fantail?
The Brine has a narrower, smaller fit (59mm lens, narrow frame) compared to the Fantail's medium-to-large fit. Both share Costa's 580 lens technology and Hydrolite grip, but the Brine is lighter with a slimmer profile and built-in ventilation, while the Fantail offers more coverage and is one of Costa's most popular fishing frames. Choose the Brine if you have a smaller face or prefer a less bulky frame.

Costa Brine vs. Costa Fantail: Which Fishing Frame Fits You?
If you're choosing between the Costa Brine 9017 and the Costa Fantail 9006, the decision comes down to fit and coverage. Both frames deliver Costa's legendary 580 lens technology, 100% polarization, and Hydrolite grip—but they're built for different face sizes.
The Brine is designed with a narrow fit and 59mm lenses, making it ideal for anglers with smaller faces or those who prefer a lighter, less bulky frame. It weighs less, includes built-in ventilation to reduce fogging, and sits closer to your face without gaps. One reviewer noted the Brine "fit my face better and with the plastic lenses much lighter" compared to the Fantail. If standard wrap sunglasses feel too large or slide down your nose, the Brine is the better choice.
The Fantail offers a medium-to-large fit with bigger lenses for maximum coverage. It's one of Costa's most popular fishing frames and provides more side protection from sun and wind. The Fantail works well for average to larger faces and anglers who want that full-wrap feel. However, it's heavier and can feel bulky on smaller faces.
Our take: Choose the Brine if you have a narrow face, want a lightweight frame, or find most fishing sunglasses too big. Go with the Fantail if you need more coverage or have a medium-to-large face. Both are prescription-ready and available with 580G glass or 580P polycarbonate lenses.
Costa Brine vs. Costa Rinconcito
The Costa Rinconcito 9016 is another fishing-focused frame in Costa's lineup, offering similar performance features at a comparable price point ($133.49–$296). Like the Brine, it's built with Costa's 580 lens technology and is prescription-ready. However, the Rinconcito has a different fit profile and may not suit narrow faces as well as the Brine's specifically designed narrow fit. If you're looking for a proven small-face frame with ventilation and Hydrolite grip, the Brine remains the safer choice. The Rinconcito is worth considering if you want to explore other Costa styles in the same performance category.
