Polarized, light-filtering glass gives your eyes a little break.

Your peepers work hard for you; give them a little love back and treat them to the Costa Del Mar Fantail Polarized Sunglasses with 580G glass lenses. The Fantail’s glare-cutting polarized lenses will keep your eyes from getting tired around the water or on the snow. At the same time, the advanced 580 technology, which blocks yellow light and boosts red, green, and blue light for excellent contrast and definition, will help you pick out details in your surroundings. You'll also enjoy the unmatched clarity of the patented Lightwave glass that is 20% thinner and 22% lighter than average polarized glass, and you'll enjoy the crystal-clear optics, as well as the fact that glass resists scratches better than plastic lenses. The co-injected nylon frames have integrated Hydrolite pads that hold tight when you sweat or get splashed by spray, while wire core temples provide stability and durability, and low-profile integral stainless steel hinges resist corrosion and keep their shape with heavy use.

Hubby's favorite sunnies

  • Familiarity: I've put it through the wringer

Love these-they are comfortable all day long and polarized so he can see into the water! Thanks Costa for awesome product!

Awesome Deal!!!

  • Familiarity: I've put it through the wringer

Have been wanting a pair for a while but they were always pricey. I came across this deal on Backcountry and couldn't pass them up. Best pair of shades I've ever had. I will never buy Oakley or Wiley X's again. Just wish I would've bought the tortoise frames also at the sale price.

Good sunglasses, with some small issues

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I got these about a month ago, and I really like them, but I don't completely love them.

Pros: Quality sunglasses, very clear lenses, they fit me pretty well, and I like the weight of them.

Cons: The lenses are slightly dark. The ear piece is slight flimsy.

I took one star off, as I ride a motorcycle, and I wont be able to use the sunglasses while riding. The ear pieces are very flimsy, and really curve inward. Those two factors make them very difficult to put on while I have a helmet on. I feel like I am going to break them.

A couple more notes, that don't directly reflect my rating, but I am hoping will be helpful. I really like the soft rubber around the bottom of the frames, as they help keep them from falling down the bridge of my nose. I don't love the silver mirror finish, but that is what was in stock, and my wife likes them. The sunglasses are little narrow, which makes them look a little funny on my face, but I also think it attributes to how well they fit.

Overall, I like them enough to keep them, and they are a good pair of sunglasses that I hope to have for a very long time.

The measurement converted into inches for these sunglasses:

can you get 1.50 bi=focal lens

I'd contact the manufacturer directly with any prescription-specific questions. That way you can be sure you're getting the most accurate info.

    Curious as to how big these are in comparison...

    Curious as to how big these are in comparison to the Jose?? I've tried the Jose on before and they are just a touch large.

    Best Answer

    I just tried both on yesterday. These are very similar in style to the Jose but a bit "blockier", the Jose has more curves. As far as size goes, I would give the Fantail's a shot they are a bit smaller and tighter fitting than the Jose. I own Jose's and I am going to buy some Fantail 580's once I have a little extra cash. Hope that helps!
