Fit Notes — AMANZI Active Kneelength
  • Size based on your bust and waist measurements. If the two measurements suggest different sizes, prioritise the bust measurement for the most comfortable fit across the upper body.
  • The wide shoulder straps and back band sit between the shoulder blades — they should feel secure but allow full arm rotation without restriction.
  • The leg height is approximately 5cm above the knee — suitable for competitive training, triathlon, and open water swimming.
  • Made from AMANZI Armor chlorine-resistant fabric — rinse in cold fresh water after every session and allow to dry naturally away from direct sunlight.
