The Costa Del Mar Tailfin 9113 sunglasses deliver performance-driven design for anglers, boaters, and anyone who demands clear vision on the water. Built on Costa's rectangular wrap frame, the Tailfin combines a modernized classic silhouette with the brand's proven fishing-focused technology.
Costa 580 Lens Technology: Built for the Water
Every Tailfin features Costa's polarized 580 lenses, engineered to filter light at 580 nanometers—the wavelength where harsh yellow light peaks. By blocking this specific spectrum, the lenses naturally boost reds, greens, and blues, delivering enhanced color contrast that helps you spot fish beneath the surface or navigate changing light conditions. The 580 technology absorbs 100% of UV light and blocks high-energy visible (HEV) blue light, protecting against eye strain and long-term damage. Costa's C-Wall coating adds scratch resistance and repels water, oil, and sweat for easy cleaning.
The Tailfin is available with both 580G glass lenses (superior optical clarity and scratch resistance) and 580P polycarbonate lenses (lighter weight and impact resistance). Multiple mirror and tint options—including Blue Mirror, Green Mirror, Copper Silver Mirror, and Gray—let you match lens color to your typical light conditions, from dawn to midday glare.
Bio-Resin Frame & Comfort Features
The frame is constructed from Costa's bio-resin material, part of the brand's Kick Plastic initiative. Derived from castor oil rather than petroleum-based plastics, bio-resin reduces carbon emissions while maintaining durability and flexibility under harsh conditions. The Tailfin's refined, chiseled edges give it a modern look, while the 8-base wrap provides peripheral coverage and shields your eyes from dust and side glare.
Hydrolite rubber temple tips and nose pads keep the frames locked in place when you're sweating or taking on spray. The textured rubber grips ensure the Tailfin stays put without a retainer strap, though finlet-inspired side shields accommodate leash attachments if you prefer extra security. Available in two sizes—57mm and 60mm lens width—the Tailfin fits a range of face shapes, from smaller to larger heads.
Prescription-Ready Performance
The Tailfin 9113 is prescription-ready, accepting single-vision, progressive, and bifocal lenses. You can add your Rx to Costa's 580 polarized lenses, combining corrective vision with the color enhancement and glare reduction that make Costa a favorite among serious anglers and outdoor enthusiasts.

Frequently Asked Questions
Are the Costa Tailfin 9113 sunglasses prescription-ready?
Yes, the Costa Tailfin 9113 is fully prescription-ready and accepts single-vision, progressive, and bifocal lenses. You can add your prescription to Costa's 580 polarized lenses in either glass (580G) or polycarbonate (580P) materials, combining corrective vision with Costa's color-enhancing and glare-reducing technology.
What is Costa 580 lens technology and how does it work?
Costa 580 lenses filter out harsh yellow light at 580 nanometers, which naturally enhances reds, greens, and blues for superior color contrast and clarity. The technology blocks 100% of UV light and absorbs high-energy visible (HEV) blue light to reduce eye strain and protect long-term eye health. This makes it easier to spot fish in the water and see detail in bright, glare-heavy conditions.
What sizes does the Costa Tailfin come in?
The Tailfin is available in two lens widths: 57mm (Small) and 60mm (Medium). Both sizes feature the same rectangular wrap design and performance features, allowing you to choose the best fit for your face shape—whether you have a smaller or larger head.
What is bio-resin and why does Costa use it?
Bio-resin is a plant-based plastic derived from castor oil rather than petroleum. Costa uses bio-resin as part of its Kick Plastic initiative to reduce carbon emissions and environmental impact. Bio-resin frames are durable, lightweight, and hold their shape under harsh conditions, making them ideal for water sports and outdoor activities.
Do Costa Tailfin sunglasses have UV protection?
Yes, all Costa Tailfin sunglasses feature 100% UV protection, blocking both UVA and UVB rays. The 580 lens technology also blocks high-energy visible (HEV) blue light, which can cause eye strain and contribute to long-term eye damage. The C-Wall coating provides additional scratch resistance and repels water, oil, and sweat.
What's the difference between 580G and 580P lenses?
580G lenses are made from glass and offer superior optical clarity and scratch resistance—they're 20% thinner and 22% lighter than average polarized glass. 580P lenses are made from polycarbonate, making them lighter, more impact-resistant, and more affordable. Both provide the same 580 color-enhancing technology and 100% UV protection; the choice depends on whether you prioritize optical clarity (glass) or weight and durability (polycarbonate).

Costa Tailfin 9113 vs. Other Costa Performance Frames
If you're considering the Costa Tailfin 9113, you might also be looking at other Costa rectangular wrap frames designed for water sports. Here's how the Tailfin compares to similar models in our collection.
Tailfin vs. Rincon
Both the Tailfin and the Costa Rincon 9018 feature rectangular wrap designs with Costa's 580 polarized lens technology and bio-resin frames. The Tailfin offers refined, chiseled edges and finlet-inspired side shields with leash attachment points, while the Rincon has its own distinct temple styling. Both are prescription-ready and available in multiple lens colors. The choice often comes down to which frame shape and aesthetic better suits your face and personal style.
Tailfin vs. Fisch
The Costa Fisch 9054 is another angler-focused frame with bio-resin construction and 580 lens options. Like the Tailfin, it's built for long days on the water with Hydrolite rubber grips and full polarization. The Fisch has a slightly different frame shape and may fit differently depending on your face structure. Both models offer the same core Costa technology—100% UV protection, color-enhancing lenses, and prescription compatibility.
Tailfin vs. Bloke
The Costa Bloke 9045 provides a rectangular frame alternative with similar performance features and pricing. Both frames use Costa's 580 lenses and are prescription-ready, but the Bloke has a different temple design and overall aesthetic. If you prefer the Tailfin's modernized classic look with chiseled edges and side shields, it's the better choice; if you want a slightly different style while keeping Costa's core technology, the Bloke is worth considering.
Why Choose the Tailfin? The Tailfin stands out for its two-size availability (57mm and 60mm), finlet-inspired side shields, and the refined, chiseled frame edges that give it a modern update to Costa's classic rectangular wrap design. It's an excellent choice if you want proven Costa 580 lens technology in a frame that's built specifically for water sports and outdoor activities, with the comfort features to keep it secure all day long.
