The LORETO Story

Named after the small, chilled-out town in the Sea of Cortez, the Costa Loreto sunglasses are full frame and adventure friendly. Whether it's hanging on the coastal cliffs for which these Costa men's or women's sunglasses get their name or on any adventure on land or sea, these durable, versatile, 100% polarized sunglasses can handle their own for any Beachcomber or Voyager.

Recommended Retainer: Fathom Cord

Additional Information

LORETO is rated 4.3 out of 5 by 86.
Rated 1 out of 5 by from Nose pieces Sounds like this has been an I'm going problem. My glasses aren't even a year old and they have been taken very good care of and both nose pieces are torn/fallen out. And for the last 4 days I have been emailing about getting a new set of nose pieces and no response. So now I'm on a "waiting list" for a phone call back since the wait time was ridiculous! We have three pairs of Costa sunglasses and these are by far the worst, and I will not be purchasing another pair of glasses after the poor quality of these, and seeing all the reviews complaining about the same problem for years and they still haven't made a change to them, that is terrible service!!

Rated 5 out of 5 by from Great fit & very stylish! I bought a pair of the Loreto Rose gold sunglasses with green plastic lens and I LOVE THEM! I was on a hunt for a good pair of sunglasses a few months ago. I went to many stores and tried on different styles and brands. I ended up loving the style of Costa's Loreto sunglasses. They fit my face really well and I can see very clearly through them. They do a great job at protecting my eyes from the sun and glare. Overall, these are amazing!!
