Mucha calidadI’m constantly on the water, inshore and offshore. I always need sunglasses and beat them pretty hard but I scored these on sale because what I love most about Costa they stand behind their product, I had to send in the same pair and they’re replacing and paid to get new lenses! Great price for a quality pair of sunglassesSunAlready have a pair of Costa Del Mar Tuna Alley shades and love them. Thought I'd give these Corbinas a shot. Glad I did! My skull is kind of big and wide so can be difficult finding sunglasses that fit well. These felt a smidge snugger than my Tuna Alleys but after wearing for a week they fit perfectly. Like all Costa Del Mar sunglasses, these came with a hard shell case, microfiber lenses wipe, and a sticker. Also love the Costa Del Mar service... when the nose piece on my Tuna's went out about six months ago, I simply sent them to the manufacturer and they repaired free of charge... I just paid shipping. Had them change out the lenses for a nominal price at the same time since I scratched them up pretty good over the years. I have purchased Costa Del Mars for gifts and everyone I've ever given them to has been impressed. Would definitely recommend these shades to friends and family, even at the steep price points.Quality of materials was on par with my last pair but the frames are a little twisted so they sit lower on my left side than my right. When the glasses are placed on a flat surface the right ear piece does not touch the surface.Have tried several top end sunglass brands, far and away the best lenses. Great warranty too, should you need it.My husband has owned these before and wore them completely out, so he’s used other brands since then. He’s so glad to have Costas back. It makes such a difference with his eyes in bright sun. Truly great product.These are by far the coldest sunglasses I've ever had in my life they're perfect it's my 2nd pair exact same ones same ones they lasted me 8 years And I still Have the old pair as a backup.
