Yes. The Arena Powerskin ST Next Ltd Edition Kneesuit is World Aquatics Approved, making it legal for use at competitions sanctioned under World Aquatics rules at all levels.

Why Buy from Allens Swimwear?
A Family Business Built on Swimming Since 1976
Allens Swimwear is a family-run business founded in 1976 by Dennis Allen and his daughter Linda Beal. It started from a genuine need. “With 2 swimmers in the family it was often difficult to find the right kit, so dad and I took the plunge and started selling to local swimmers at our local pool in Kingsbury out of a suitcase and we’ve never looked back.” Today, Linda, her husband Richard, and three of their children Danny, Will and Jenna still run the business together. The suitcase may be long gone, but the founding principle of helping swimmers get the right kit remains exactly the same.

Fit Notes — Arena Powerskin ST Next Women's
- Use the Torso Loop (D) as the primary sizing guide — this determines how the suit sits across the shoulders and through the body.
- If your measurements fall between sizes, speak to a member of staff at Allens who will be happy to advise on the best fit.
- The eco-friendly recycled fabric is lighter and faster than the previous ST generation — the suit should feel close-fitting and supportive with excellent freedom of movement.
- Low-profile seams should lie completely flat against the skin with no rubbing or pressure points during competition.
- The ST Next’s longer-lasting compression means the suit retains its compressive properties for longer than many competing suits when properly cared for.
- The suit should be completely wrinkle-free when correctly fitted — any bunching or gathering indicates the suit is too large.
- Allow 10–15 minutes to put on correctly for the first time. Take care with fingernails and jewellery to protect the fabric.
- Do not use sunscreen, oils, or petroleum-based products before putting on the suit as these degrade the fabric.
- Rinse in cold fresh water immediately after each use. Do not machine wash, tumble dry, iron, or dry-clean.
- Unsure? Contact our team or call +44 1827 330600. Speak to a member of staff at Allens if you are unsure.
Frequently Asked Questions — Arena Powerskin ST Next Women's
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.
