Born On the Water in the fishing capital of the world, Costa sunglasses are made for those who don't just spend their lives on the water, they come to life on the water. Each pair is packed with polarized, color-enhancing 580 lens technology. The result? Less haze and enhanced contrast and clarity. Available in glass (580G) for superior clarity and scratch resistance or a lightweight, impact-resistant polycarbonate (580P), it's like seeing in high-definition. Experience sunglasses for life's great adventures. Rincon II is a technical evolution of our #1 best seller Rincon, giving watermen more functionality and versatility in the same aesthetic they love. New micro side shields and hooding provide a heightened level of coverage, minimal light leak and protection from the elements. Vented nose pads increase ventilation across the frame, reducing the risk of fogging. Also new to this frame is our transition from spot glued rubber to double injection, ensuring your frames never delaminate and last in the roughest of elements.
