The exclusive Parabolic Pressure Control System is a reinforced system designed to allow the polymeric blade to bend following a parabolic curve. Suited to all depths when freediving. The ONE blade is super responsive thanks to its bi-concave shape that works like a spring. System One's special tail profile makes the blade steady allowing for perfect energy transmission to the blade.
Available in 5 sizes: 38-40, 41-42, 43-44, 45-46, 47-49
