Costa Sunglasses reign supreme around the water. And they have for years. Just take a look at what most professional waterman wear. Wether it be a fisherman, charter captain or dive boat operator, Costa Sunglasses offer superior performance in this environment. A recent trip to Saint Lucia allowed my wife and I to test out a couple of new options from Costa in the very environment they were made for. Sunshine and ocean. And this Eastern Caribbean island had plenty of both. Hiking in the Petons, exploring the coastline by speedboat, Helicopter operations, SCUBA diving and Sailing. Through it all the new Rinconcito frame remained comfortably on my face despite 50 MPH winds while on a 700HP Cigarette Boat. And the 580 Polarized lens provided 100% UV protection while reducing glare around the water. The Rinconcito is the little brother to the larger Rincon frame that I reviewed last summer. Although similar in construction, I do prefer the medium sized frame of the Rinconcito.
