B Labs developed the Axiom in collaboration with top athletes from Vertical Blue—one of the world’s most prestigious freediving competitions. The result is a competition fin designed with one goal in mind: less drag, more speed.

It is built on a highly modular carbon fiber base that meets F1 standards—stiffer and with faster energy return than conventional carbon fiber constructions. The narrow blade design minimizes vertical drag and maximizes return speed with every fin stroke. Manufactured using a high-pressure autoclave process to ensure a uniform, bubble-free structure and stable power transmission.
