Fit Notes — AMANZI Acceler8 RIZE Racing Jammer
  • This is a World Aquatics (FINA)-approved racing jammer — it is designed for competition use and should not be used for training as this will significantly shorten the lifespan of the suit.
  • Size based on your waist and hip measurements. The Acceler8 RIZE is a compression suit and will feel tighter than a training jammer — this is normal and expected for a racing suit.
  • The elasticated waistband with hidden drawstring provides a fully adjustable fit. Ensure the drawstring is secured before racing to prevent the suit from shifting during dives and turns.
  • Silicone leg grippers hold the suit in position during competition. Do not fold or roll the leg openings, as this can damage the grippers over time.
  • Care: rinse in cold fresh water immediately after use. Do not machine wash, tumble dry, wring, or expose to direct sunlight for extended periods. Store flat and dry.

Frequently Asked Questions — AMANZI Acceler8 RIZE Racing Jammer

Measure your waist and hips in centimetres and match to the size table above. UK/US sizing is the primary reference — AUS, D, and F equivalents are also shown. Racing suits are compression garments and will feel tighter than training swimwear. Speak to a member of staff at Allens if you are unsure.

Yes. The AMANZI Acceler8 RIZE Racing Jammer is World Aquatics (formerly FINA) approved, meaning it meets the requirements for use in sanctioned competitive swimming events. Always check with your governing body or meet officials if you are unsure whether a specific suit is permitted for your competition.

The Acceler8 RIZE is designed for competition use only. Using it for regular training will significantly reduce its lifespan and compromise its hydrodynamic and compression properties. For training, we recommend the AMANZI training jammer range, which uses chlorine-resistant fabric built for regular pool use.

Racing jammers are designed to be considerably tighter than training swimwear. The high-level compression is intentional — it provides muscle support, reduces lactic acid accumulation, and improves hydrodynamics. If the suit is uncomfortable to the point of restricting movement or breathing, try the next size up. If in doubt, speak to our team at Allens.

Rinse thoroughly in cold fresh water immediately after every use. Do not machine wash, tumble dry, wring, iron, or expose to direct sunlight for extended periods. Store flat and dry, away from sharp objects. With proper care the hydrophobic coating and compression properties will be maintained for longer.

Yes. The size range covers boys' sizes from size 22 (Boys 6 AUS) through to size 30 (Boys 14 / Extra Small adult), as well as adult sizes from 30 to 36.
