The material of the BM30 fin is a lightweight and reactive technopolymer, offering performance similar to carbon fiber-based composites, eliminating the problem of material brittleness. The technopolymer is elastic with high shape memory and retains its original geometry without permanent deformations.

The geometry of the BM30 blade has a 30° angle, ideal for facilitating the fins on the surface and supporting the natural angle of the ankles during diving. The thin, differentiated profile creates optimal flex, while the small stabilizers placed at the tip of the blade aid in water flow.
