BALLAST is rated 4.6 out of 5 by 13650.
Rated 5 out of 5 by from Simply AWESOME! This is my 5th pair of Costa's and now my favorite everyday sunglasses. So very light and excellent clarity even though they are poly lenses. My other Costa's are all 580 glass and this is the first 580p. LOVE EM! Fit is awesome, clarity is awesome and weight is spot on. My go to Costa's had been my pair of Hammerheads but these now are my go to Costa's. Can't beat the quality and warranty. I know this after having two previous pair that were 12 plus years old and damaged. Costa stood behind their product after all that time and offered replacements or I could pay the difference for 580 glass. Outstanding company. Can't wait to get my Next pair.

Rated 4 out of 5 by from Almost perfect..almost I have had my pair for a couple years. My chief complaint is that the nose fittings want to slide off when I am cleaning the lens. My other concern is that I have a couple dings in the lens from them falling to the pavement and, of course, they are right in my line of sight. I haven't yet checked to understand the cost of lens replacement. Other than that, they are wonderful in the sun. I live in Florida and so my glasses go everywhere I go, every day.
