Mares Power Plana Fin

The Mares Power Plana Fin is their tec fin and offers outstanding features. Comprised of natural rubber, this fin is virtually indestructible and is perfect to be paired with a drysuit. This high density composition of this fin makes it negatively buoyant, something that is a favourite with drysuit users.

Not only extremely durable and effective, this fin is also designed with comfort in mind. The full shape foot pocket is designed to be as comfortable as possible at all times and comes with a bungee strap on the rear. This bungee strap not only makes donning and doffing the fin extremely easy, it also naturally adjusts to changes in depth and pressure to make sure that you always have a snug fit.

Key Benefits

  • Virtually Indestructible Comprised of natural rubber, these fins are extremely durable and virtually indestructible to make them perfect for even your most rugged dives.
  • Comfortable The full shape foot pocket is designed to be as comfortable as possible both in and out of the water to give you great support while kicking.
  • Easy Donning and Doffing The back of the heel has a bungee strap which makes putting the fins on and taking them off super easy. The bungee straps also work to adjust to changes in depth and pressure to always give a snug fit.
  • Negative Buoyancy The natural rubber composition of the fin is high density and gives the fin negative buoyancy, something sought after by drysuit divers.

Who is the Mares Power Plana Fin For?

This Mares tec fin is ideal for drysuit divers due to its high density and virtually indestructible nature. The natural rubber composition of the boot is extremely durable and will take on any dive conditions imaginable. The rubber is also high density to give the fin negative buoyancy.
