Smooth in use and providing reliable
propulsion, the Mantis is a basic
strap fin for scuba diving and
skin diving.

  • Sense like the foot Foot pocket designed
    close Foot pocket designed

    The foot pocket is formed using a thin and pliant rubber material. This makes the fins easy to put on and take off.

  • Fin work and efficiency Middle-range blade

    Designed with a blade length shorter than ordinary fins, these also shorten the time for which the rubber material flexes to help accomplish nimble and efficient fin work. Moreover, to achieve maximum performance in these middle-range fins of the sense of pliant grip obtained when using rubber fins, the height of the keel at the rear has been slightly lowered, for a design that yields greater comfort.

  • Greater propulsion Hybrid rubber

    To enable these fins to powerfully, yet smoothly, deliver tenacious propulsive power, Gull’s innovative production methods integrate different pliant and resilient types of rubber for the foot pocket, blade, and ribs.

  • Strong in a downkick Rib shape

    The ribs on the Mew are designed with the down kick in mind. At this time when power is most easily converted to propulsion, Mew Fins firmly catch the water. Providing pleasing response to strong or subtle kicks, they suit a variety of conditions and are loved by both power divers and occasional divers, who have different leg strengths.

DX spec fin buckle

The buckle is now easier to deal with. With a better-designed center guide, the quick-release locking mechanism can be latched and detached even by weak and tired hands. Less force is also required with the improved strap adjustment button. As required, you can easily fine tune the strap fitting.

Jet holes (two locations)

Jet holes funnel water rearwards, reducing turbulence and side planing when you kick. To achieve a powerful jet flow, these new-design jet holes have wide entrances and narrow exits.
