Indigo offers a modular approach to fin technology. Our fin designs allow divers to change the fin's stiffness for greater control and the ability to customize the look of the fin.  Indigo"s TAC fin - Carbon Stiffener Inserts can be added for an overall more rigid fin.  Defiant XT fins have 6 different color inserts plus a standard and rigid stiffener option.  Discover your perfect fin set-up with Indigo Industries.
