I have worn Costas for a little over 21 years. I wore them before they were trendy and friends used to make fun of me for wearing boating glasses. Times have changed. Lol.

I just replaced a pair of Triple Tail glasses with Amber 580 glass lens. It was replaced under warranty because the prior pair of triple tail glasses lasted 11 years of hard boating and offshore fishing and the lenses were finally starting to fade in the corners.

I have had several other Costa sunglasses as had my brother and several friends. Myself included think the quality has gone down a little bit but they are still great glasses. I prefer the amber lens over grey for boating but that's my preference.
