SPORT Modular Monofin Fiberglass

The SPORT Modular Monofin Fiberglass is the natural next step for freedivers ready to experience real monofin performance without a PRO-level investment. A fiberglass blade with a 28° foot pocket angle delivers genuine efficiency in both pool and open water, while the detachable SPORT Silicone Foot Pockets work interchangeably with your SPORT Bifins blades, giving you the freedom of traveling without the added bulk. Available in soft and medium stiffness.

Please note: If you already own the SPORT Bifins or SPORT Silicone Foot Pockets, you only need the SPORT Modular Monofin Blade Fiberglass.

Detachable foot pockets
The SPORT Silicone Foot Pockets connect and disconnect from the blade quickly and securely, letting you switch between monofin and bifins training with one pair of foot pockets.

Angled blade
A 28° blade angle puts your feet in a more natural, comfortable position while finning, reducing fatigue and improving efficiency.

Fiberglass
A premium, full-size fiberglass blade delivers the flex, responsiveness, and durability you need for pool and open water training—at a price point that makes a monofin’s power genuinely accessible.

Stabilizing rails
Integrated blade rails stabilize your kick and reduce lateral movement through the water, making each stroke more efficient and consistent.

Travel-friendly
The detachable blade and foot pockets pack down more compactly than a fixed monofin, making the SPORT Modular Monofin Fiberglass a practical choice for freedivers who travel with their gear.

Care Instructions

• Rinse the monofin thoroughly in fresh water after every use to remove salt, chlorine, or sand. Do not use hot water, detergents, or aggressive cleaning agents.
• Dry in a shaded, well-ventilated area. Do not dry in direct sunlight, near heat sources, or in a clothes dryer.
• Store the monofin flat in a cool, dry place. Do not bend the blade or store it upright in a position that could warp its shape.
• Avoid contact with sharp objects, which can scratch or cut the fiberglass blade or silicone foot pockets.
• Do not walk on land or rocky surfaces while wearing the monofin.
• Do not place heavy objects on top of the blade and avoid stepping on it.
• Do not leave the monofin in a hot car as heat can damage both fiberglass and silicone.
• If sand or dirt gets between parts during use, disassemble, rinse, and reassemble before your next session.
• Inspect the foot pockets and assembly hardware regularly for wear. Replace parts if damaged.
• For transport, use a padded monofin bag to protect against impacts and scratches.
