With over 85% of triathlon competitors coming from a running, cycling or other sport background, blueseventy recognises that many athletes possess a denser leg make up due to well-exercised and established thigh muscles and dense calves. Heavier legs leave the majority of triathletes at a distinct disadvantage in the first discipline. Our goal is to give the world a faster swimming experience, so the Axis suit has been developed with the focus on centralizing buoyancy and balancing out the buoyancy zones.

The body has a large buoyancy zone in the torso, two big air bags we know as the lungs! With such large natural flotation it makes sense for those with a buoyancy centered on the upper body, to focus the extreme additional suit buoyancy in the lower extremities. By placing higher buoyancy materials in the hips, thighs and lower leg the goal of Balanced Buoyancy is achieved. By increasing the height of the lower body and lifting the legs and hips, the body is in a more streamlined position allowing for a more efficient swim stroke.

  • Balanced Buoyancy for increased body alignment and performance delivered through anatomically located blueseventy ‘molecular neoprene’, designed to deliver superior buoyancy over typical neoprenes
  • Increased feel of the water and propulsion with forearm propulsion panels
  • Anatomically correct flex reach panels for maximum flexibility and arm detachment from the main body
  • Low friction neck to promote comfort and increase sighting comfort
  • Easy release ankle system for faster transitions
  • Special Femme Fit upper body panels to accommodate the female form.
  • Maximum wetsuit thickness of 5mm (USAT Legal)

Balanced buoyancy suits are specifically designed with triathletes in mind. Triathletes are often heavier in the legs due to the muscles developed through cycling and running, which can create drag if they are not able to maintain good body position. Balanced Buoyancy wetsuits like the Axis use higher buoyancy materials in the hips, thighs and lower leg. This increases the height of the lower body, lifting the legs and hips and putting the body in a more streamlined position, reducing drag and allowing for a more efficient swim stroke.
