Improved, ultra-responsive fiberglass fins, created with the same material as the Molchanovs Competition Monofin 3 Fiberglass. Paired with our upgraded Molchanovs hand-built foot pockets, available in standard EU sizes or custom-sized to your desired fit with an open heel for unparalleled ankle flexibility.
Molchanovs CB2 Fiberglass are made with UHC Fiber, a high-performance fiberglass using over 50 times the pressure of other fiberglass long fins, and the same fiberglass we use in our freediving record-breaking Competition Monofin 3 Fiberglass.
Design updates to the blade include a unique bottleneck shape, resulting in the blades feeling smoother than ever before with a more powerful reaction due to their efficient transition in the water. Other updates include improved layering of the fiberglass, using a “wave” layering structure that allows for smooth transition and even stiffness between the layers. This creates a more efficient and responsive movement throughout a kick cycle. They also come in the new M-stripe design in four vivid colors.
Our CB2 Fiberglass are of the same standard as most carbon fins on the market, making them an ideal choice for freedivers who desire quality but are not in the market for carbon fins.
We took customer feedback and focused on making the new generation of Molchanovs hand-built foot pockets even more comfortable than before. Updated Comfort Lining and increased space for the toes give your feet some much-needed relief, even with the tightest fit. They are also UV-resistant and heavy-duty, and have built-in arch support that decreases fatigue and keeps the foot in the perfect position, maximizing small-muscle use and minimizing drag.
