Churchill® Swimfins became one of the world’s best-selling Swimfins when the sport of bodyboarding was introduced in 1971. the Swimfins became a favorite among riders from professional to novice because of the thrust and performance that came from the fins. over several decades, the fins haven’t differed from its original shape but have introduced many colors including its iconic blue & yellow color scheme. made popular by several world champions, Churchill® then trademarked its world known colors in 1994, as well as the popular color scheme black & yellow.
