  • Description

    The Apeks RK-3 traditional all rubber design has been the standard for Coast Guard, Special Ops, Military and Public Safety Divers for decades.

    The blade material is developed to hold up in the harshest environments, temperatures, and bear the worst abuse. The short wide blade provides maximum forward thrust while it maintains great manoeuvrability. The vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke.

    The fins come standard with high-quality stainless steel spring straps.

    Comes in three sizes; Medium, Large and Super.
