Product Details

In nature, a King Tide requires the perfect alignment of Earth and moon to create once-in-a-lifetime views and opportunities for watermen. Like their namesake, the King Tide 6 is designed to give you the ultimate advantage on the water. ​ ​
​
Made for watermen who demand performance in every sport, the King Tide 6 features a medium wrap with removable side shields for optimal viewing on and off water. Shark-inspired venting achieves a near impossible zero-fog effect. Top of the line sweat management and drains keep your view dry and unobstructed. Non-skid hooding means they stay in place on any surface wet or dry. ​ ​
​
All this has made King Tide 6 the crowning achievement of Costa’s 40 years on the water, utilizing the research and innovations from every frame that came before it. ​ ​
​
​Rule the water.
