Sizing Tips

Finding Your Perfect Fit – Your wetsuit should feel snug but never restrictive. For the best performance and comfort, you want a close fit with no loose areas or wrinkles. Height and weight are your starting points, but your body shape and swimming style matter too. Between sizes? Give more emphasis to weight over height.

We've refined our size chart based on thousands of real-world fittings and athlete feedback. The result? A much more precise size chart that better matches your natural shape and swimming style.

Our suits now offer:

  • More tailored fit through the shoulders and chest
  • Better sizing options for different body types
  • Enhanced comfort around key movement areas

    • Height (in)
