The Atomic Aquatics SplitFin is now available in a full-foot model. The Full-Foot SplitFin is lightweight — lighter than other full-foot split fin designs — yet delivers results comparable to the larger open heel fin. Designed to deliver the highest performance ever achieved by a full-foot fin, the Atomic Aquatics Full-Foot SplitFin meets and exceeds user expectations whether being used for snorkeling or scuba diving, and has proven to be the highest performing full-foot fin in the world. Using the patented Nature's Wing design Atomic Aquatics has added a unique light-weight batten and blade design that delivers incredible performance and more power.
