SOUTH SEA is rated 4.6 out of 5 by 18.
Rated 5 out of 5 by from The difference between Ok half way through our Marlin season my last pair of tuna ally costas fell in the ocean while looking down to bring in a live bait , so I got online and orderd a pair of the new style south sea which suite my style a lot more ! Plus I got the strap to ensure I'd keep them lol. Anyway while hunting for Marlin in our local waters the bright conditions and slight chop made it hard spot any sign and luckily for great superior uv and polarised attribute of Costa shades I was able to spot a nice fish smashing the surface , I usually do not promote products but I have to say that my new shades played a contributing factor in spotting the beast three times at long distance and in a slight choppy sea, which resulted in my team ( team VALHALLA) out of Tairua New Zealand landing this very nice blue . Thanks Costa !

Rated 2 out of 5 by from Bull! Looks great and the 580 glass lenses are very clear. They need to come in more than one frame size though!
