Diving Gear - Apeks RK 3 Fins is a pair of brand new set of fins designed alongside the US Military. RK3 fins are made from thermoplastic rubber providing great power and efficiency in the water.   Spring straps are fitted as standard for easy donning and doffing as well as being much more robust than their rubber counterparts.   Apeks RK3s are made from a single piece of molded thermoplastic rubber, ensuring maximum durability in all conditions. The compound used is slightly softer than other fins of a similar design on the market making them much springier, providing a little more 'snap' on the down stroke.
