Specs and Features

The Fantail Pro is a testament to Costa’s dedication to superior functionality and design. Here’s an overview of their main specs before we dive into how they perform in real life.

Frame Material: A bio-resin nylon frame combines durability and environmental consciousness.

Lens Material: 580G Lightwave Glass. This lens provides excellent clarity while not being too heavy. As a rule of thumb, glass lenses are heavier than polycarbonate (plastic) lenses. Costa claims their 580P lens is 20% thinner and more than 20% lighter than their competitors’. I’ve found the Costa Fantail to keep up with that promise with the clarity being unmatched and I’ve never had the feeling of the shades being too heavy even after a full day out on the water.

Polarization: Employing Costa’s patented technology, these glasses dramatically reduce glare, especially off water, enhancing color contrast. Here’s where Costa’s experience of producing sunglasses for four decades comes into play: the harmful blue light and the harsher yellow is filtered out, while red and green is enhanced.

Vented Design: Cleverly placed vents, combined with side shields and hooding, prevent lens fogging during intense activities. I’ve found the temples to be wide enough to block out the majority of the light but still provide enough ventilation around them.

Lens Color Options: (note: not all lens colors are available with all frame colors) Different environments and activities necessitate varied vision capabilities. Costa acknowledges this with a range of lens colors for the Fantail Pro:

Blue Mirror: Perfect for open waters, this lens provides maximum contrast and color in bright conditions.

Green Mirror: A versatile choice for mixed light conditions, be it inshore fishing or sight fishing.

Gray: A general-purpose lens, it excels in glare reduction while preserving color saturation and natural contrast. Costa claims it’s ideal for very bright sunlight but I’ve found it to be an excellent allrounder and to work well with overcast skies as well.

Copper Silver Mirror: Excellent allrounder, and surprisingly good in low light conditions from my experience.

Sunrise Silver Mirror: This is my favorite when it comes to lowlight conditions.

Size: Frame width: 133mm, Bridge Width: 15mm, Lens Width: 60mm, Lens Height: 41.8mm, Temple Arm Length: 120mm.

Adjustable nosepads

RX available

Warranty: Two years limited warranty during which your sunglasses will be repaired or replaced by Costa. Learn more here.

Price: $264 – 284 (non prescription)

Glass vs. Plastic Lenses

When choosing sunglasses, the debate often arises: glass or plastic (polycarbonate) lenses? Each has its merits. Glass lenses, like the 580G used in the Fantail Pro, are renowned for superior clarity. They tend to be more scratch-resistant than their polycarbonate counterparts, ensuring they remain unscathed from minor abrasions.

On the downside, glass lenses are heavier, but Costa’s Lightwave Glass manages to mitigate this by being exceptionally lightweight. Polycarbonate lenses, however, are known for their durability and resistance to shattering, making them a good choice for high-impact activities. But when it comes to fly fishing, where clarity is paramount, the premium glass lenses of the Fantail Pro truly shine.

Why They Stand Out in Real Life

Now that you know about the basic specs of the Costa Fantail Pro and the advantage of their glass lens, let’s dive deeper into what I love about these sunglasses in real life when hitting the water.

First off, these fly fishing sunglasses don’t come cheap. At $284 they play in the same league as the Oakley Clifden Prizm Polarized. Here’s what you get for it: first and foremost a high quality glass lens that provides excellent glare reduction, polarisation and protection from harmful rays.

Secondly, you can tell that’s Costa shades are really tailored to fishermen. Adjustable nosepads make sure your sunglasses stay in place even when you’re fighting a big fish. The fit of the sunglasses is snug but not too tight to prevent air from coming in (which helps prevent fogging). At the end of the temples you have holes for a leash (it would be nice to have a leash come with them as the Oakley’s do).

  • Unmatched polarization enhancing visual clarity.
  • Array of lens colors for diverse needs.
  • Sturdy yet lightweight frame.
  • Advanced venting system to combat fogging.
  • Deep-rooted commitment to environmental stewardship.


  • Size L will work for most people but since there is no XL version, consider going for the Blackfin PRO if your face is wide
  • The frames come with a protective case and cleaning cloth but a leash would be a nice upgraded (since the Fantail Pro come with holes in the temples)

Conservation Efforts 

Beyond exceptional eyewear, Costa’s heartbeat resonates with conservation. Their “Kick Plastic” campaign targets reducing oceanic plastic waste by advocating sustainable alternatives. Partnering with entities like Ocearch (which promote the protection of sharks), Costa further fosters marine research and education.

Yes, the Fantail Pro are an investment at almost $300. Is is a worthy investment. I would say yes. The eyes are your most important sense in fishing and from my experience it’s not only crucial to protect them from flies or debris but investing in a high quality polarized lens, will improve your success on the water. If you like the shape of the Costa, the Oakley Splitshot and the Suncloud Boone might also be good options for you.
