The RK3 HD is the latest offering in the RK3 fin category. It is made from higher-density material compared to the standard RK3, making it stiffer and heavier, ideal for diving with a dry suit.

- Compact and highly durable for use in harsh conditions
- Improved foot pocket with springs for ease of use with cold hands or thick gloves
- The design has been the standard fin for the military, special forces, coast guard, and public safety for decades
- Short and wide blade that provides maximum forward thrust while maintaining great flexibility
- The ventilated design of the blade reduces resistance during uphill movement and enhances thrust during downhill movement

- The blade material is designed to withstand the toughest conditions, temperatures, and hardships
- Two large openings for easy storage of the fins with a carabiner
