Molchanovs bifin blades made with the same ultra-high compression fiberglass as used in their legendary monofins. The UHC Fiber is a high-performance fibreglass made to our specifications using over 50 times the pressure of other fibreglass long fins. The blades are shaped by hand to give it its unique tip flexibility. The result is a softer, more responsive, yet more powerful fin.

The blades are paired with Molchanovs custom foot pockets, attaching them with the same technique used on our monofins allowing us to eliminate the heavy rails and increase the flexibility of the blade. Our open heel design promotes increased efficiency by allowing for greater mobility in the ankle and use of the smaller muscles of the calves and ankles.

The desired fit determines the tightness of the foot pockets. 3 options are available:
Comfort: Ideal for recreational dives and long training sessions. If you intend to put them on for long periods of time, choose this option. Comfortable for about 45-60 min.
Normal: A medium tightness, ideal for focused training sessions and competitions. Comfortable for about 20-30 min.
Sport: The tightest fit available, maximising power transfer, specially for competition dives. Comfortable for about 10-15 min.

The blades are made to withstand strong underwater moves in any direction and consequently provide powerful thrust. However, don’t walk with the fins on rough rocks and don’t drop heavy solid objects, such as cameras with underwater gear, weights, etc. – the blade could crack or break. We suggest washing off salt and keeping the fins away from the strong sun and heat.
