Fiber/Carbon Bifins : Spearfishing, Apnea, Snorkeling, Competitions

Carbon and fiberglass bifins for spearfishing, freediving and competition
Looking for bifins that are more powerful, lighter and more responsive than polymer fins? POwerfins designs and co-produces fiberglass and carbon blades for spearfishers, freedivers, experienced swimmers and competitors. Every pair comes fitted with its foot pockets, so you can step up to performance without changing your gear.
Carbon or fiberglass bifins: which one to choose?

Carbon bifins (from €295): the carbon blade is lighter and more responsive. It gives back more of the energy of your kick, which reduces fatigue on long sessions and at depth. It is the choice of freedivers and spearfishers looking for the best efficiency.
Fiberglass bifins (€195): excellent value, available in black, blue and green. Ideal for discovering performance bifins, training regularly and progressing before moving up to carbon.
Custom-made bifins (€390): foot pocket and blade tailored to your foot, with a 35 or 45 mm pocket for optimal hold and comfort. Discover the custom-made carbon bifins.

Which discipline?

Spearfishing: power to chase fish and efficient kicks to stay discreet and save your breath.
Freediving and apnea: smooth, low-fatigue propulsion for descents, ascents and static or dynamic sessions.
Competition and sport swimming: stiff, responsive fins for trained swimmers who want speed and an optimized blade angle (18 degrees).

Choosing your blade hardness

Soft (D1): flexibility and comfort, to start out or swim for a long time without tiring.
Medium (D2-D3): the right balance of power and ease of kicking, for most users.
Hard (D4-D7): maximum power, for experienced swimmers and freedivers with the leg strength to use it.

Choosing your size
Our bifins are available from 35-37 to 48-50, with Pathos foot pockets already fitted. Size ranges overlap: if you are between two sizes, choose based on the hardness and the socks or wetsuit you usually wear, or contact us before ordering and we will be happy to advise you.
