In nature, a King Tide requires the perfect alignment of Earth and moon to create once-in-a-lifetime views and opportunities for anglers. 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. Non-skid hooding means they stay in place on any surface wet or dry.
