Cyclone Scuba Dive Rubber Fins/FN590 & Frameless Mask/MK100 & Cobra 100% Dry Whistle Snorkel/SK680:
From the demands of the divers with military specifications, we are proud to recommend to you our solid black open heel rubber fin.
This fin is made of antioxidant compound rubber that enhances the performance while keeping the blade consistently in appropriate hardness.
The draining holes reduce resistance when you kick the water in making a forward propulsion.
They are also helpful in gathering full kicking strength by moving the power to the front part of the blade.
The enlarged channels and ridges provide balanced propulsion for diver movements.
The one hand releasable swivel buckles and the intensified fin straps improve comfort and allow for easy adjustments.
