RTS APNEA:
Our RTS XL fin has a special length of 88 and a width of 19 cm, a composition more adapted for the practice of freediving, it has a rough surface textured on both sides, the advantage of this fin is that thanks to its textured surface it reduces skidding in the flutter and maintains a constant push, this fin has been designed for competition fishing where you fish at a high pace and the flutter is constant.

Manufacturing System:
For the development of our fins we have created our own manufacturing methods, developing a system that allows an increase of 10% more reactivity of the fin, lowering its weight compared to the previous model by 10%, thus achieving a more effective fin. , stronger and more efficient. Video
​
All our fins are manufactured in 5 different hardnesses.
