STINGRAY CARBONStingray Carbon fins feature carbon fiber blades manufactured using the infusion technology with innovative double vacuum process. Thanks to this technology, carbon fiber stands are perfectly impregnated in the resin, without the risk of forming micro bubbles and with an optimal distribution of the resin itself. In addition, percentage of necessary resin is considerably reduced with a great increase in performance of the blade combined with a very comfortable thermo-rubber footpocket. Aside from not tiring out the diver’s leg while kicking on the surface for extended periods, the Stingray Carbon blades push the diver the most during descents and ascents even n great depths. The interchangeable blades are available in three degrees of stiffness: 20 soft, 25 medium and 30 hard.
