Arena Girls Powerskin Impulso Kneesuit - Black/Teal

Measure your child’s chest (A), waist (B), hip (C), and torso loop (D) using a soft tape measure directly against the skin. Use the Torso Loop (D) as the primary guide and compare all measurements to the sizing table above. Age is shown as a guide only — always use body measurements as children develop at very different rates. Speak to a member of staff at Allens if you are unsure.

The Torso Loop is measured by running a soft tape measure over one shoulder, down the front of the body, under the crotch, and back up to the same shoulder. This is the most important measurement for a kneesuit as it determines how the suit sits across the shoulders and through the body.

Always select by body measurements. The age ranges shown are a guide only — children develop at very different rates and age alone is not a reliable indicator of the correct size. Measure the chest, waist, hip, and torso loop and compare to the sizing table, using the torso loop as the primary guide.

A junior racing kneesuit should feel firm and compressive but comfortable throughout a full competition day. It should be completely wrinkle-free when correctly fitted — any bunching or gathering indicates the suit is too large. The straps should sit flat on the shoulders with no pulling, and leg hems should end above the knee in line with World Aquatics regulations.

Yes — both the Arena Powerskin Impulso and ST Next Girls’ Kneesuits meet FINA/World Aquatics specifications and are approved for use in all sanctioned competitive swimming events. Always check with your event organiser for any local age group rules regarding tech suits in competition. Speak to a member of staff at Allens if you need further guidance.

If your child’s measurements fall between two sizes, speak to a member of staff at Allens who will be happy to advise on the best fit. Arena racing kneesuits are designed to fit closely — a suit that fits correctly should feel firm and supportive without restricting breathing or movement.

Arena racing kneesuits are competition suits and are not designed for regular training use. Using a tech suit for training will degrade the fabric and reduce its lifespan significantly. Reserve it for races and competition warm-ups. Arena offer a wide range of junior training swimsuits for everyday pool use.

Rinse the suit in cold fresh water immediately after every use. Do not machine wash, tumble dry, iron, or dry-clean. Store flat and dry, away from direct sunlight. Avoid contact with sunscreen, oils, and petroleum-based products. Do not wring or twist the suit. Handle with care when putting on and taking off to protect the fabric.
