In 2020, we launched the Competition Bifins 2 Carbon, which were designed and fine-tuned by Alexey Molchanov with a unique ‘bottleneck’ shape that allows the blade to transition quickly and efficiently between strokes. After many successful world records were performed with the CB2 Carbon in the 2021 competition season, we have redesigned them to create the Competition Bifins 2x Carbon. Updates include new colors and an improved blade layering structure, giving the CB2x Carbon blades an updated concept of stiffness that favors smaller amplitude, low-effort kicking. Shorter freedivers also have the option to choose a smaller blade cut with 10% less surface area and adjusted bottleneck shape to improve maneuverability and spend less power and energy on kicks. The CB2x are paired with Molchanovs Hand-Built footpockets for unparalleled comfort and flexibility. Available in 6 stunning new colors.

Tailor your footpocket to your foot, your blade cut to your body, and your blade color to your personality with the CB2x.

Desired Fit Guide

The desired fit determines the tightness of the foot pockets. Three options are available:

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 2 hours of wear.

A medium tightness, ideal for focused training sessions and competitions. Comfortable for about 1 hour of wear.
Sport: The tightest fit available, maximizing power transfer, especially for competition dives. Suitable for about 30 minutes of wear.


Care Instructions

All equipment should be rinsed in fresh water and placed out of direct sunlight and heat. Do not place heavy objects on top of the bifins. For more information, please see how to care for your freediving bifins and monofin 和 how to travel with them. AA 1-year limited warranty applies.
