The Costa Del Mar Blackfin Pro 9078 sunglasses represent a significant upgrade to one of the most trusted frames in fishing eyewear. Built on the foundation of the original Blackfin—a favorite among anglers for over a decade—the Pro version adds six performance-driven enhancements designed to keep you on the water longer and fishing more effectively.
Costa 580G Glass Lens Technology
Every Blackfin Pro comes exclusively with Costa's 580G polarized glass lenses, the gold standard for optical clarity on the water. The 580 technology works by blocking yellow light at 580 nanometers while enhancing reds, blues, and greens, delivering sharper contrast and better color definition in any environment. These glass lenses are 20% thinner and 22% lighter than average polarized glass, yet they offer superior scratch resistance thanks to the C-Wall coating that repels water, oil, and sweat. All lenses provide 100% UV protection and 100% polarization to eliminate reflective glare—essential for sight fishing and spotting structure beneath the surface.
Available in multiple lens colors including Blue Mirror (ideal for bright, full-sun conditions), Green Mirror (high contrast for sight fishing), Gray (true color perception), and Copper Silver Mirror, you can match your lenses to your fishing conditions. The encapsulated mirror design places the reflective layer between glass layers for crystal-clear, scratch-resistant performance.
PRO Series Performance Features
The Blackfin Pro's six angler-approved upgrades set it apart from the standard model. Fully adjustable, vented nose pads let you customize the fit while reducing fogging—a game-changer during long days in variable conditions. Integrated sweat channels and eyewire drains direct moisture away from the lenses to maintain clear vision. The wide temples feature side shields and hooding that block stray light from every angle; as any experienced angler knows, side light makes it harder to see into the water through polarized lenses, so maximum coverage matters.
The improved Hydrolite temple pads use a new formula that gets tackier as it becomes wet, ensuring your sunglasses stay put even when conditions get rough. Pre-molded metal keeper slots at the temple ends make it easy to attach a retainer without the struggle of fitting sleeves over the arms. These frames are built from Costa's bio-resin material (derived from castor oil) as part of their Kick Plastic initiative, offering lightweight durability with an environmental conscience.
Fit & Prescription-Ready Design
The Blackfin Pro features a large fit with a 60mm lens width, 41.8mm lens height, 16mm bridge, and 121mm temple length—designed for average to wider faces. The pillow-shaped, full-rim frame provides maximum coverage without feeling bulky. These sunglasses are prescription-ready, so you can add single vision, bifocal, or progressive lenses to enjoy Costa's legendary clarity with your exact vision correction.
"These lenses are some of the best that can be found in sunglasses today." — Wired2Fish review
Whether you're sight fishing the flats, running offshore, or spending long days on the river, the Costa Blackfin Pro 9078 delivers professional-grade optics and all-day comfort. Backed by Costa's limited lifetime warranty, these sunglasses are built to become your go-to pair for years to come.

Frequently Asked Questions
Are the Costa Blackfin Pro 9078 sunglasses prescription-ready?
Yes, the Blackfin Pro is fully prescription-ready. You can order these frames with single vision, bifocal, or progressive prescription lenses to match your vision needs. The frame's design accommodates prescription lens installation while maintaining the same 580G polarized lens technology and UV protection.
What is Costa 580G lens technology and how does it work?
Costa 580G lenses use glass composition with patented technology that blocks yellow light at 580 nanometers while enhancing reds, blues, and greens. This delivers sharper contrast, better color definition, and enhanced clarity compared to standard polarized lenses. The lenses also absorb harmful high-energy blue light (HEV), offer 100% UV protection, and are 20% thinner and 22% lighter than typical polarized glass.
What's the difference between the Blackfin Pro and the original Blackfin?
The Blackfin Pro features six key upgrades: vented and fully adjustable nose pads (vs. fixed pads), sweat management channels, eyewire drains, extended side shields and hooding, improved stickier Hydrolite grips, and metal keeper slots. The Pro is also slightly smaller (60mm lens width vs. 62mm) and is only available with 580G glass lenses, while the original offered both glass and plastic options.
What size face do the Blackfin Pro sunglasses fit?
The Blackfin Pro features a large fit designed for average to wider faces. The frame measures 60mm lens width, 41.8mm lens height, 16mm bridge width, and 121mm temple length, with an overall frame width of 135mm. The wide temples and wraparound design provide maximum coverage and side light protection.
How do the adjustable nose pads on the Blackfin Pro reduce fogging?
The Blackfin Pro's nose pads are both fully adjustable and vented. The small vents built into the nose pads improve air circulation around the frame, which helps reduce fogging during temperature changes or high-activity conditions. You can also adjust the pads to customize the fit and optimize airflow for your face shape.
Are Costa Blackfin Pro sunglasses good for fishing?
Yes, the Blackfin Pro is specifically designed for serious fishing. The wide temples with side shields block stray light that makes it harder to see into the water, the 580G glass lenses enhance underwater visibility and color contrast for spotting fish, and features like sweat channels and improved Hydrolite grips keep the frames comfortable and secure during long days on the water. Many professional anglers consider them among the best fishing sunglasses available.

Costa Blackfin Pro 9078 vs. Other Costa Fishing Sunglasses
Choosing the right Costa sunglasses depends on your face size, fishing style, and whether you want the latest PRO Series technology. Here's how the Blackfin Pro 9078 compares to other popular Costa fishing frames in our collection.
Blackfin Pro vs. Costa Fantail 9006
The Fantail and Blackfin are Costa's two most iconic fishing frames, and both have earned legendary status among anglers. The key difference is that the Blackfin Pro features six PRO Series upgrades that the standard Fantail lacks: vented adjustable nose pads, sweat management channels, eyewire drains, extended side shields, improved Hydrolite grips, and metal keeper slots. The Blackfin Pro also has wider temples that provide superior side light blocking—critical for sight fishing. If you want the absolute best performance features and don't mind the investment, the Blackfin Pro is the clear choice. The Fantail remains an excellent option for anglers who want proven Costa quality at a lower price point.
Blackfin Pro vs. Costa Tuna Alley 9009
The Tuna Alley offers a similar large fit to the Blackfin Pro and is another favorite for offshore and inshore fishing. However, the standard Tuna Alley doesn't include the PRO Series enhancements—no adjustable nose pads, no sweat channels, and no improved Hydrolite formula. The Blackfin Pro's customizable fit and anti-fog vented nose pads make it better suited for all-day wear in variable conditions. That said, the Tuna Alley's lower price and availability in both glass and polycarbonate lenses make it a solid alternative if you're budget-conscious or prefer lighter polycarbonate lenses.
Blackfin Pro vs. Costa Reefton 9007
The Reefton features taller and wider lenses than the Blackfin Pro, making it ideal for anglers who prioritize maximum lens coverage. However, it lacks all six PRO Series upgrades, meaning you won't get the adjustable fit, sweat management, or improved grip technology. The Blackfin Pro's wide temples and side shields actually provide better peripheral light blocking despite the slightly smaller lens size. If you have a larger face and want the biggest possible lenses, consider the Reefton. But for most anglers, the Blackfin Pro's combination of coverage, fit customization, and performance features make it the superior choice.
Our Recommendation: The Costa Blackfin Pro 9078 is the best choice for serious anglers who spend long days on the water and want the most advanced fishing sunglasses available. The PRO Series upgrades—especially the adjustable nose pads and sweat management system—deliver measurable performance benefits that justify the investment. If you're looking for a more budget-friendly option, the Fantail or Tuna Alley are excellent alternatives with the same legendary 580 lens technology.
