Free Diving Fins Cressi Gara Modular Sprint

The blade of Sprint, like the Impulse blade, is made of a single thermoplastic elastomer, although it would be more correct to refer to an angled sublayer and an overlay.

The sublayer follows the shape and dimensions of almost the entire fin. It has a uniform thickness and a flexible longitudinal propulsion wing of variable length.

In contrast, the so-called overlay covers the propulsion wing selectively and has a thickness that slopes from the maximum value to zero longitudinally towards the tip of the blade.
