Neptira T300 Carbon Fiber — Pure Carbon Fins

Designed for freedivers who demand efficiency, responsiveness and effortless movement underwater, the Neptira T300 Carbon Fiber Fins combine a lightweight pure carbon fiber blade with a streamlined long-blade design for powerful and efficient propulsion.

Made with pure carbon fiber, the T300 provides an excellent balance of stiffness, energy return and flexibility. Each kick is designed to transfer your leg power efficiently into forward thrust, helping reduce unnecessary energy consumption during descent and ascent.

With a 93 × 20 cm long-blade profile, the T300 is engineered for smooth, controlled movements and efficient propulsion, making it suitable for freediving, depth training and underwater exploration.
