Molchanovs Fiberglass Bifins F2 $390.00 Molchanovs Fiberglass Bifins F2 (2021) The new Molchanovs F2 Fiberglass Bifins are the latest added products to the Molchanovs diving gear collection. Alexey Molchanov himself helped design the F2 bifin, and as you would expect from Molchanovs, these fibreglass bifins are one of the best – if not the best fibreglass bifins on the market. Be it recreational or competitive, the Molchanovs Fiberglass Bifins F2 won’t fail you. Its ultra-high compression fibreglass blades are made from UHC fibre, known as high-performance fibreglass. This makes the F2 softer, stronger, and much more durable than other fins available in the market. If you want to experience smooth and top-level freediving at a very reasonable cost, you should get yourself a pair of the Molchanovs Fiberglass Bifins F2 NOW!
