Ab Activators

  • Helps to promote optimal body position in water.

Maximized Support Seam Construction

  • Improves the linkage of the muscular kinetic chain.
  • Support seams enhance the link between muscles of the upper and lower body.

  • Seam runs across the lower back with an identifiable ‘X’ shape.
  • The construction of the seams provides feedback to the swimmer, helping to maintain a better position in the water and a high-leg kick.
