Molchanovs PRO Bifins 3 Fiberglass - Available Now

Efficiency, customizability, and comfort - introducing the PRO Bifins 3 Fiberglass. Premium lightweight bifins designed for your every freediving adventure.

• Description

  The PRO Bifins 3 Fiberglass are the premium all-around fiberglass bifins - ideal for fun diving, training, and competition use. Lightweight foot pockets are assembled by hand to stay gentle on your feet and are paired with premium 100% UHC fiberglass blades. The Molchanovs Education System prioritizes power on the bifin back kick, so we updated the blade-layering pattern, added size-graded blades, and increased the blade angle - all to contribute to a more impactful front and back bifinning technique. Efficiency, customization, and comfort are now all wrapped up in a sleek little package. Available in 6 vibrant accent colors.

  Choose between standard or custom sizes.

  For freedivers who want premium bifins specifically for competition performances, we recommend the PRO Hyper Bifins in carbon or fiberglass.

  Comfortable hand-built foot pockets

  While most foot pockets are created from a mold in a factory, our PRO foot pockets, with their original pointed design, are assembled by hand from different pieces of rubber and soft micropore. This makes them ultra-comfortable and gentle on your feet. Additionally, stiffer rubber on the upper part of the foot pockets, paired with the glued connection to the blade, enhances energy transfer, making you more 'one' with your blade.

  Premium 100% UHC fiberglass

  The durable fiberglass blade is designed for low-effort + high-propulsion finning and continues to be in the top-performance range for both fiberglass and carbon blades. Now with an updated blade-layering pattern for each blade size to match the stiffness.

  Size-graded blades

  Blade sizes are now tailored to your height - freedivers on the shorter or lighter side have more maneuverability and save power on each kick with shorter blades, while freedivers on the taller or heavier side have longer blades for more efficient kicks.

  Larger blade angle

  The blade angle is now 28° – this increased angle makes your front kicks feel more effortless while enhancing the power of your back kick by promoting a better streamlined position. Additionally, it compensates for less flexible feet and ankles.

  New double-sided design

  The unmistakable minimalistic stripes on the front of the blades are now complemented by the 'molchanovs' text on the back, matching the chosen blade accent color for an even more striking design.

  Choosing Bifin Blade Size

  Molchanovs offers three different bifin blade sizes: Small, Regular, and Large. Choose the blade size according to your height and weight listed in the table below for the perfect balance of maneuverability and power spent on kicks. Small blades feature 5% less surface area than regular blades while Large blades have 5% more surface area than Regular blades. Each size’s blade length and width are adjusted to maintain balance, including the ‘bottleneck’ shape to maintain blade efficiency.

  Please note: While the blade-layering structure of all blade sizes are the same, the reduced surface area of Small blades can make them feel softer than Regular blades, and the extended surface area of Large blades can make them feel stiffer than Regular blades.

  Choosing Bifin Blade Stiffness

  Blade stiffness depends on your height, weight, technique, experience, training goals, and blade size. Below are general tips on how to choose the right stiffness. If you are not sure, e-mail info@molchanovs.com with a video attached of one of your dives for a recommendation.

  Soft: Suitable for smaller and lighter freedivers, freedivers with less lower-body strength, and also for experienced freedivers with excellent ankle-driven technique. Softer blades are more economic in terms of energy consumption, although it mostly remains a preference among freedivers with more strength whether to choose a soft or medium stiffness.

  Choose Soft stiffness if:

  • You’re a smaller and/or lighter freediver with less lower-body strength
  • You dive in little to no current and with no extra gear (underwater camera, spearfishing equipment, thick wetsuit, etc.)
  • You use a more ankle-driven technique and want efficiency

  Medium: Suitable for larger and heavier freedivers, freedivers with more lower-body strength, or for freedivers who need more power.

  Choose Medium stiffness if:

  • You’re larger and/or heavier and have lower-body strength or need more power
  • You’re unsure whether to choose soft or medium fins
  • You’re a safety diver, underwater photographer, or spearfisher
  • You dive with extra gear

  Hard: Suitable for freedivers with a lot of lower-body strength who need more power.

  Choose Hard stiffness if:

  • You have a strong lower body and require a lot of power on your dives
  • You dive with a lot of gear
  • You’re a spearfisher
