Freediving fins PIENNE

The BM30 fin materialA lightweight and reactive technopolymer, unique to date, that offers performance similar to a carbon fiber-based composite while eliminating the well-known problem of material brittleness. The technopolymer used is so elastic and has such a high shape memory that if - in an absurd demonstration - we were to look at the blade after it has been wound on itself, it would still have its original geometry when released, without any permanent structural deformation. which could compromise its performance.Blade geometry of the BM30The blade of the SEAC BM30 fins is tilted by 30°. This more accentuated angle is ideal for both facilitating surface fins and supporting the natural inclination of the ankles when diving. In addition, the ultra-thin, differentiated profile creates optimal flex. Small stabilizers located at the end of the blade, at the point of greatest water flow, prevent the fin from drifting sideways without compromising proper blade flex.Material of the BM30 foot pocketLike the successful Motus series, the BM30 foot pocket is made of two different materials, a stiffer one on the sole for stability and a softer one on the upper for maximum comfort during prolonged use.Geometry of the BM30 foot pocketThe BM30 foot pocket is optimized for blade placement at a 30° angle. The short water rails allow the blade's technopolymer to express all its reactivity and flexibility.
