Molchanovs Sport Monofin CM3

The Custom Made Molchanovs Sport Monofin CM3 is undoubtedly the best choice for elite freediving competitors!

This new monofin has a more extensive and stronger blade-base and a softened edge for an almost effortless powerful kick – definitely designed for the big win! This Molchanovs fibreglass sports monofin resonates excellence. The lighter, thinner and more responsive blade is made of ultra-high compression fibreglass. The customised foot pockets are amazingly comfortable, optionally made with arch support and soft rubber linings. This monofin can quickly and safely take you to any depth you want! Another incredible and high-performance product from Molchanovs!

The 2021 Molchanovs Fibreglass Competition Monofin CM3

They are designed by the multiple World Record Holder and Freediving World Champion, Alexey Molchanov himself. The Molchanovs CM3 Sport Monofin is undoubtedly one of the best competitive freediving monofins in the world – if not THE single best competition monofin in the world! Only the finest artisans in the industry assemble the hand-layered and highly compressed fibreglass blades. The customised foot pockets are amazingly comfortable and come with optional arch support and soft rubber linings. The monofin has been proven and tested by its designer Alexey Molchanov and other world champions and record holders like him many, many times over. It comes as no surprise that the Molchanovs monofins are the first choice of champions!


Special features of fibreglass Sport Monofin:

  • Super strong and flexible high-class fibreglass plate.

  • Special foot pocket design for ergonomic and comfortable diving.

  • Maximum boost and propulsion with minimal effort because of the foot pocket angle.

  • Hand,- and custom made for the perfect fit.

  • Used, and tested by the best freedivers in the world.

Professional swimmers and freedivers repeatedly tested the original models and, of course, personally by its developer and world champion Alexey Molchanov. Pretty much all top freediving athletes around the world acknowledge this sports monofin as one of the best – if not the single best high-performance freediving monofin in the world.

Additionally, the Molchanovs fibreglass monofin is handcrafted by a master with many years of specialist experience producing underwater fins. There are four colours of fibreglass plates to choose from; black, blue, pink and now yellow. All the Molchanovs monofins are slightly positively buoyant, eliminating the chance of losing it in the depths of the sea.

The production time of the freediving monofin is 4 to 6 weeks, but when needed (and when possible), we can consider the urgency of your order. Do you need the monofin urgently? Please get in touch with us via the contact page.


The NEW Sport Monofin Options!

When Molchanovs informed us about the new features available for the new monofins, we couldn’t wait to get our hands on the first models, and now that we’ve seen and tested them ourselves, we are sure this new and improved will be huge in freediving.

Not only does the new freediving monofin come in a brand new yellow, pink and blue colour, but there are now three new options available.

The new stripes on the monofin blade.

The new monofin stripes/rails are more than just a new design option. The small rubber strips look amazing, while they also protect the blade from scratches in the pool and help control the flow of water along the monofin blade. And, of course, for sure helps in lifting the ‘looking cool’ factor.

Obtain a straighter foot position with the supinator.

Both the instep supinator and micropore are incredible developments in freediving. They are developed having in mind ‘you should not feel the monofin!’ The arch support supinator instep is an insert in the foot pocket similar to a shoe insole that keeps the foot in a more natural position. If you have any problems with bending the legs inwards while kicking, this arch support will possibly prevail over this.

The micropore lining is an extra low friction top layer.

All monofin freedivers know the problems of ‘painful’ feet when training for 20 or 30 minutes. The foot pockets have to fit quite tied on the foot to ‘feel’ the movements and have direct propulsion the moment you kick, but this can result in very painful feet. The micropore lining is a small pad and extra layer at the top of foot pockets made of a softer rubber with less friction. The first time you’ll use a monofin with an extra micropore pad, you’ll ask why no one used this before – it’s such a tremendous difference.

I believe the Molchanov Sports Edition fin is the best engineered fin for freediving. So many fins that freedivers use have actually been designed for fin swimmers but when I use the Molchanov I get the best power for effort ratio than any other fin.

    Great training monofin 🙂
    After having tested some other training models, I really found this one to be better in many ways.
    Good balance, and so much pleasure using it !
    I also wanted to highlight how great Vincent and his team were when it came to advise me in the models/size to choose.
    Great contact and service 🙂
    Can’t wait to take an opportunity and visit them for some freediving sessions !
