Arena Womens Powerskin ST Next Kneesuit - Black

Measure your chest (A), waist (B), hip (C), and torso loop (D) using a soft tape measure directly against your skin. Use the Torso Loop as the primary guide and compare all measurements to the sizing table above. 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 racing suit as it determines how the suit sits across the shoulders and through the body.

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

A tech suit should feel firm and compressive but wearable 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 suit should feel tight but should not restrict breathing or cause pain. Seams and panels should lie flat with no rubbing or pressure points.

Arena racing suits 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 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.

Arena racing suit sizes (18–34) do not directly correspond to standard clothing sizes. Always use body measurements to select the correct Arena size. The international size equivalents shown in the table (France, USA/UK, Italy, Germany) are provided as a secondary reference — always prioritise body measurements.

Yes — the Arena Powerskin ST Next meets FINA/World Aquatics specifications and is approved for use in all sanctioned competitive swimming events. It is also notable as the first ever World Aquatics approved racing suit made with recycled fabrics. Always check with your event organiser for any local rules regarding tech suits in competition.
