Fit Notes — AMANZI Acceler8 RIZE Racing Kneelength
  • This is a World Aquatics (FINA)-approved racing kneelength — designed for competition use only. Regular training use will significantly reduce the suit's lifespan and performance properties.
  • Size based on your bust and waist measurements. Racing suits are compression garments and will feel considerably tighter than training swimwear — this is expected and intentional.
  • Shoulder and back straps are positioned to sit between the shoulder blades, allowing maximum freedom of arm movement during competition.
  • Silicone leg grippers keep the kneelength in place during dives and turns. Do not roll or fold the leg openings, as this will damage the grippers.
  • Care: rinse in cold fresh water immediately after use. Do not machine wash, tumble dry, wring, or expose to prolonged sunlight. Store flat and dry.
