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 the 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, utilising the research and innovations from every frame that came before it. ​ ​
