Description
xPrecision-fit comfort straps deliver a secure, unrestricted fit no matter how many events are on the schedule. The moderate compression level is calibrated to support without fatigue, so you can perform at your best from heat one to the final. All-day wearability is built in from the design stage, not added as an afterthought.
Bonded dual-layer panels and optimised seamlines reduce drag and move with the body rather than against it. Leg grippers keep the suit in its correct position throughout every stroke and turn. Together these elements work in synergy to enhance fit, flexibility and race-day performance.
The LZR Pulse Fabric is built with durable wrapped yarns that help the suit retain its shape across repeated competition use. An advanced water-repellent coating sheds water efficiently, keeping the suit light in the pool. You can rely on this kneeskin to perform race after race without compromise.

Yes. The Fastskin LZR HyperPro Printed Kneeskin has been fully approved by World Aquatics and is legal for use in sanctioned competition at all levels.
Speedo race suits fit differently from training suits and are designed to feel firm when dry. We recommend checking our Speedo Fastskin LZR HyperPro Kneesuit Size Guide before ordering, as sizing can vary from your usual Speedo size.
The HyperPro Printed Kneeskin uses moderate compression, which sits between a training suit and a high-compression elite race suit. This makes it a strong choice for developing competitors who want race-suit performance with greater all-day comfort across long meets.
Proper aftercare is important for maintaining the compression and water-repellent properties of any race suit. Please follow the guidance at full product aftercare guide to get the best life from this kneeskin.

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.

To find the correct LZR HyperPro Kneeskin size, use a soft measuring tape and take all measurements directly against your skin. The Body Loop is the most important measurement for a kneeskin — always measure this first and use it as the primary guide.
Note: If your measurements fall across different size brackets, always use the Body Loop as the primary guide. All measurements are body measurements, not garment measurements.

Watch our step-by-step guide to taking accurate body measurements for the perfect LZR HyperPro Kneeskin fit.
Yes. The Speedo Fastskin LZR HyperPro Kneeskin is fully approved by World Aquatics (WA) and is legal for use in all sanctioned competitive swimming events for women. It has been developed by Speedo Aqualab and is built to compete at all levels of the sport, from club and county racing through to national and international competition.
The Speedo Fastskin LZR HyperPro Kneeskin for women is available in sizes 18 to 30. These are Speedo's own sizing system, not standard UK dress sizes, so it is important to use body measurements rather than your usual clothing size. Refer to the sizing table above and use your Body Loop measurement as the primary guide to find the correct size.
The Body 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 kneeskin as it determines the torso length and whether the flexible comfort straps will sit correctly on the shoulders without pulling or twisting during competition.
The Women's LZR HyperPro Kneeskin is the adult version, available in sizes 18 to 30 and cut for an adult female body shape. The Girls' Junior version is available in sizes 26 to 32 and is proportioned for younger swimmers aged approximately 7 to 14. Both suits share the same key features — comfortable compression, flexible comfort straps, bonded dual layers, and World Aquatics approval — but the adult and junior sizing systems are different and should not be interchanged.
The LZR HyperPro Kneeskin should feel firm and compressive but comfortable throughout a full competition day. The flexible comfort straps should sit flat on the shoulders with no pulling or rubbing, the bonded seamlines should lie flat with no pressure points, and the suit should be completely wrinkle-free when correctly fitted. The leg hems should sit above the knee in line with WA regulations. If the suit has any bunching or gathering, it is too large.
The Speedo Fastskin LZR HyperPro Kneeskin is designed for all competitive swimming events and all four strokes. It is engineered to suit all skill levels, strokes and distances, making it an ideal choice for women competing at club, county, regional, or national level who want a reliable, comfortable World Aquatics approved racing kneeskin that performs race after race.
The LZR HyperPro sits within the Fastskin racing range and is designed to deliver all-day comfort with moderate compression, making it suitable for all skill levels and distances. It features flexible comfort straps, optimised seamlines, bonded dual layers, and a shape-retaining lightweight fabric built to last race after race. Swimmers looking for higher compression for elite competition may wish to explore other suits in the Fastskin range — speak to a member of staff at Allens for guidance.
Yes. The LZR HyperPro Kneeskin's moderate compression and all-day comfort make it an excellent choice for a swimmer's first Fastskin racing kneeskin. The flexible comfort straps are anchored with precision to reduce rubbing and provide a comfortable, unrestricted fit throughout a full competition day, making it considerably easier to wear compared to higher compression suits — without sacrificing the performance benefits of a World Aquatics approved tech suit.
The LZR HyperPro Kneeskin is a competition racing suit and is not designed for regular training use. Using it for training will degrade the water repellant coating and reduce the lifespan of the suit significantly. Reserve it for races and competition warm-ups to maintain its performance properties. Speedo offer a wide range of women's training swimsuits designed for everyday pool use.
Rinse the suit thoroughly in cold fresh water immediately after every use to remove chlorine and salt. Do not machine wash, tumble dry, iron, or dry-clean. Store the suit flat and dry, away from direct sunlight. Avoid contact with sun cream, body oils, or petroleum-based products as these degrade the water repellant coating. Consistent care after each use is essential to maximise the lifespan and performance of the suit.
