Description
xHyperforce™ is the first-ever tensoelastic racing fabric, delivering high compression at 50% stretch alongside exceptional flexibility. TPU fibres woven directly into the material are naturally hydrophobic, permanently repelling water to reduce drag and preserve suit performance even after repeated use. The result is a lighter construction that maintains its fit and compression race after race, preventing the fibre fatigue that degrades ordinary race suits.
The all-new FLEX-MAX ergonomic shoulder straps are engineered to reduce pressure and maximise stroke freedom across every discipline. By working in harmony with the extraordinary stretch of Hyperforce™, they optimise hydrodynamics for a smoother, faster swim. This combination of strap design and fabric technology delivers unprecedented mobility without sacrificing the secure, race-ready fit you need on the blocks.
New internal taping provides powerful support that elevates legs and hips into an optimal body position, reducing frontal resistance through the water. Alongside this, Hyperforce™ suits offer a durable life cycle by preventing over-stretching and fibre fatigue, maintaining compression longer across repeated races. The suit is also available in long torso sizes for a near-custom fit.

Arena race suits are sized differently to training suits and should fit very snugly on. We recommend consulting our Arena Powerskin Veloce Womens Size Guide for Arena-specific sizing guidance, and noting that the Veloce is also available in long torso sizes for a near-custom fit.
Yes. The Powerskin Veloce is fully approved by World Aquatics for use in sanctioned competitive pool events.
Arena has engineered the Veloce to go on in under 10 minutes. Take your time working the suit up evenly from the feet, smoothing the fabric as you go. Avoid pulling sharply on the straps, as this can stress the fibres. Dry hands and a race suit bag can make the process easier.
Hyperforce™ fabric is designed for durability, but proper aftercare is essential to preserve compression and hydrophobicity race after race. See our full product aftercare guide for full guidance on rinsing, drying and storing your race suit.
View our full swimwear product aftercare guide to ensure you look after your race suit properly.
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.

Take all measurements directly against your skin using a soft tape measure. Use the Torso Loop (D) as the primary sizing guide — this determines how the suit sits across the shoulders and through the body.
If measurements fall between sizes, use the Torso Loop as the primary guide. Speak to a member of staff at Allens if you are unsure.

All measurements are body measurements, not garment measurements. Use the Torso Loop (D) as the primary sizing guide. Speak to a member of staff at Allens if you are unsure.
Watch our guide to measuring for the Arena Powerskin Veloce 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 Veloce meets FINA/World Aquatics specifications and is approved for use in all sanctioned competitive swimming events. Always check with your event organiser for any local rules regarding tech suits in competition. Speak to a member of staff at Allens if you need further guidance.
