NOTE: As usual, I, Snorkel Bob, tried’em all. These MOFLEX™ Snorkel Fins are one more result of the largest snorkel research facility in the world. Like no other component of snorkeling, fins can fool you. MOFLEX™ combines design & engineering to yield the best fins available today. And I, Snorkel Bob, mean excellence in power-to-weight ratio, strength, tracking, BHP, torque, flex, separation, lift & spread. You will find this level of quality & performance cheaper nowhere.
