I'm no sales person for sure but I'm curious about who uses quality sunglasses on the water vs. who uses $3 dollar general glasses. I have been wearing Costa's for 3 years now and love them! I love the company, the quality, and their over all goal to make every day activities easier due to having the proper eye protection. I have a set of fantails with 400G blue mirrored glass lenses, as well as a pair of blackfin bl10 dark black lenses with the 580G lenses. Many of you might have no clue what I'm talking about but I do honestly suggest you look in to an investment in a quality pair of sunglasses. I am a life time Costa customer, how about you? Is any one else realizing the quality sunglasses can make a huge difference on the water, as well as on your eyes. If anyone has questions about Costa's or just wants to argue about how their Oakleys are soooo much better I'd love to talk with you. I had to learn all about Costa's product line at a previous job so feel free to hit me with questions.
