I've been freediving with carbon fiber fins since the early 90's. Back then I was using one of the few prototype pairs available.
These fins were a giant step in the art of moving underwater.
For the past 20 years I've fine tuned my technique and my adaptation to composite fins, always looking for the best blades.
I've been faithfull to a fin maker for 12 years until I discovered the Trygons blades.
With the experience, I'd say that producing a good blade require an accurate process that only hi-end machines associated to a rigorous control and the use of the best fabrics/ resins can guarantee.
Trygons is nowadays the only company able to meet these creterias.
These fins accept no compromise and are a delight to use.
