I have had them all....Costas, Ray Bans, Maui's u name it...I was strictly a Costa guy until they refused to hone their lens warranty, because they discontinued the frame!...I use Wyle X's- Frames Direct.com has great deals on them.....I have 2 pair, one polarized and one non- polarized....The Wyle's frames are very robust, glass is very good...I use them for Ice, Lake and Sea....no complaints...
Protect your eyes, good sunglasses give u more time on the water, keep u fresher and are a real safety factor...nothing worse than a migraine due to glare....
