Description: In nature, a King Tide requires the perfect alignment of Earth and moon to create once-in-a-lifetime views and opportunities for anglers. Like their namesake, the King Tide 8 is designed to give you the ultimate advantage on the water. Made for elite anglers that demand the most from every cast, the King Tide 8 features a full 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 8 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.
