The blades of the Minimal 350 FS-30 have a hardness of 30 medium, made from 100% top-quality carbon T300, and are 20mm longer towards the heel than traditional blades.

The blade angle is 29° unlike regular carbon blades that form a curve instead of an angle. Their dimensions (786 x 190 mm) are suitable for use at a similar hardness in demanding underwater fishing.

The fixed-width water rails of the new design direct the water to flow along the blade, achieving effective propulsion and the underwater hunter feels as if they are moving "on rails." Meanwhile, the dimensions and the dual parabolic bend of the blade allow for movement with absolute flexibility.

The new C4 - H.Dessault 350 fins are made from thermoplastic rubber and thanks to their unique design weigh only 350 grams for sizes 41-42. They are the lightest thermoplastic rubber fins on the market today. The ergonomic design is characteristic of the C4 - H.Dessault style. They feature a pre-shaped 3-degree angle to enhance comfort and efficiency.
