Oceanic Manta Ray Fins

Description

Oceanic Manta Ray Fins

Inspired by Nature. Built for Power.

The Oceanic Manta Ray Fins are inspired by the ocean’s most effortless swimmers and designed to replicate the biomechanics of marine animals. Built with advanced materials that provide strength, flexibility, and efficiency, the Manta Ray delivers powerful propulsion while remaining lightweight and durable.

Designed for divers who want speed, control, and efficient movement underwater, the Manta Ray combines a strong techno-polymer blade, energy-returning Power-X System, flexible Power Channel, and winglets along the blade to maximize thrust and improve maneuverability with every kick.

The Manta Ray’s techno-polymer blade is engineered to deliver the strength needed for powerful underwater propulsion while keeping the fin lightweight and easy to control.

This advanced material helps maximize power, speed, and efficiency, giving divers strong thrust without unnecessary weight or bulk. The result is a fin that feels responsive, durable, and efficient throughout the dive.

The Power-X System is designed to work like the tendons and joints of marine animals. During the downstroke, the material flexes to store energy. Before the upstroke, it releases that stored energy to help optimize propulsion.

This energy-returning design helps make each kick more efficient, supporting smoother movement and stronger forward motion underwater.

The Power Channel uses flexible material to help direct water flow off the back of the blade. Inspired by the elasticity of skin, this design helps increase thrust by controlling how water moves through the fin during each kick.

For divers, this means more effective propulsion and better use of energy while moving through the water.

Winglets along the length of the blade help improve water control, increase efficiency, and support better maneuverability. This design helps the fin feel more stable and responsive, making it easier to adjust direction and maintain control underwater.

The Soft-Pad Heel Strap is designed for comfort and ease of use. Its ergonomic finger loop makes the fins easier to put on and remove, even when wearing thick neoprene gloves.

This makes the Manta Ray practical for different dive conditions, from tropical diving to cooler-water dives where gloves may be needed.

The Easy Buckle Adjustment system allows more than 2 in / 5 cm of precise adjustment for a custom fit without tools. This makes it easier to fine-tune the fit around your dive boots and get a secure, comfortable setup before entering the water.

Size Chart

Please refer to the size chart below to help you choose the correct size. For the best comfort and performance, we recommend selecting a size that fits securely with your dive boots without excessive movement.

Who It’s For

The Oceanic Manta Ray Fins are ideal for divers who want a powerful, efficient and lightweight Open Heel fin.

They are particularly well suited to divers who value strong propulsion, responsive energy transfer, manoeuvrability and precise adjustment in a durable fin designed for regular scuba diving.

What Sets It Apart

What makes the Manta Ray different is the way its systems work together. The Power-X System manages blade flex and energy return, the Power Channel controls water flow, and the winglets improve stability and manoeuvrability.
