The H4 not only looks different, but also performs like no other fin. The precisely calculated and evolved template and the precision Swiss engineering used to create it have resulted in unprecedented speed and control.
The high density carbon fibre used is light and strong, converting more energy into acceleration than other fins. In addition, the unique template, which is different between the center and sides, makes it easy to control even at high speeds, which are difficult to control.
The H4 is an ultra-high performance, high-end model that is completely different from anything that has come before.
