How to Measure

To find your correct Speedo Fastskin LZR Pure Valor 2 Kneesuit size, use a soft measuring tape and take all measurements directly against your skin. If you fall between two sizes, size down for maximum competition compression, or size up for easier donning. The Body Loop measurement is particularly important for kneesuits — if you are on the larger end of your size, consider sizing up to avoid strap pull.

  • A
    Body Loop Measure over one shoulder, down the front, under the crotch and back up to the same shoulder. This gives the torso length needed for a kneesuit.
  • B
    Hip Measure at the widest part of your hips and seat, keeping the tape horizontal.
  • C
    Chest Measure across the fullest part of your chest, keeping the tape horizontal.
  • D
    Waist Measure at the narrowest part of your natural waist.

Note: Fastskin racing kneesuits are designed to fit tightly — this is intentional and is part of the suit's performance compression. The suit will feel very firm upon first wear and will ease slightly with use.

Fit Notes — Speedo Fastskin LZR Pure Valor 2 Kneesuit
  • The Speedo Fastskin LZR Pure Valor 2 Kneesuit is a competition racing suit designed to fit significantly tighter than a training or leisure swimsuit. A snug, compressive fit is correct and intentional.
  • The hips are the tightest bottleneck: the hips are the widest and hardest part of the body to pull a highly compressive tech suit over. If the hip size is too small, you risk tearing the expensive fabric or breaking the bonded seams while pulling it up.
  • Compression without restriction: the Speedo Fastskin LZR Pure Valor is engineered with lightweight fabric and moderate compression to support muscle groups and streamline your profile. Sizing primarily by the hips ensures the compression panels on the thighs and glutes lock into place correctly without restricting your kick.
  • Core alignment: the internal seams and hip joints of the kneesuit must align perfectly with your greater trochanter (hip bone) to sit properly. If the hips don't align, the upper body and shoulder straps will pull down too hard, restricting shoulder mobility.
  • Hips (most important): wrap the tape measure firmly around the fullest part of your hips and glutes, keeping the tape parallel to the floor.
  • The suit should be completely wrinkle-free when correctly fitted. Any bunching or excessive gathering indicates the suit is too large.
  • The leg hems should end above the knee in line with WA regulations and feel snug but not restrict blood flow.
  • Allow up to 15–20 minutes to try on correctly. Take care when pulling up the suit to avoid damaging the Lamoral® coating.
  • Do not use petroleum-based products, oils, or creams before putting on the suit — these degrade the water-repellent coating.
  • Rinse in cold fresh water immediately after each use. Do not tumble dry, iron, or dry-clean.

Frequently Asked Questions — Speedo Fastskin LZR Pure Valor 2 Women's Kneesuit

Yes. The Speedo Fastskin LZR Pure Valor 2 Kneesuit is fully approved by World Aquatics (WA) and is legal for use in all sanctioned competitive swimming events, including club, county, national, and international competitions. Always check with your event organiser for any additional local or federation rules.

The Speedo Fastskin LZR Pure Valor 2 Kneesuit is available in both Closed Back and Open Back styles. The Closed Back offers greater upper body compression and is preferred by swimmers who want additional core and back support. The Open Back offers more freedom of movement across the shoulders and is popular with backstroke and butterfly swimmers. Size 18 is only available in Open Back.

Both suits share the same sizing and are part of the Speedo Fastskin LZR range. The LZR Pure Intent 2 is Speedo's flagship suit featuring maximum compression, designed for elite sprint competition. The LZR Pure Valor 2 offers moderate compression and a more flexible construction, making it better suited to distance swimmers, multi-eventers, and those competing across multiple races or events in a session.

We recommend selecting your size based on your body measurements — using your hip measurement as the primary guide. Speak to a member of staff at Allens if you are unsure.

The Body Loop is measured by running a soft tape measure over one shoulder, down the front of your body, under your crotch, and back up to the same shoulder. This measurement determines the torso length of the suit and is the most important measurement for a kneesuit, as it determines whether the suit will sit comfortably on your shoulders without pulling.

Speedo Fastskin kneesuits are sized by body measurements, not standard clothing sizes. Always use your chest, hip, waist, and body loop measurements from the table above rather than your usual dress or swimwear size. The suit will feel considerably tighter than a training swimsuit — this is normal and is a deliberate part of the suit's performance design.

No. The Speedo Fastskin LZR Pure Valor 2 Kneesuit is a competition-only racing suit. Using it for regular training will significantly shorten the lifespan of the suit and degrade the Lamoral® water-repellent coating. Reserve the Pure Valor 2 exclusively for races and competition warm-ups. Speedo offer a separate range of endurance training swimsuits and kneesuits for regular pool use.

The LZR Pure Valor 2 features Lamoral® Space Tech coating that delivers 6x more lasting water repellency than previous Valor models. To maximise longevity, rinse thoroughly in cold fresh water after every use, store flat and dry away from direct sunlight, and avoid sharp nails or jewellery when putting the suit on. Do not tumble dry, iron, or dry-clean. Reserve the suit exclusively for competition.

The Pure Valor 2 Kneesuit is designed for distance and multi-event competitive swimmers. Its moderate compression and flexible LZR construction make it particularly well-suited to events from 200m upwards across all four strokes and individual medley, where a full range of movement is essential. Sprint specialists may prefer the higher compression of the LZR Pure Intent 2 Kneesuit.

Rinse the suit thoroughly in cold fresh water immediately after every use. 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, fake tan, or petroleum-based products as these will degrade the Lamoral® coating. Do not leave the suit sitting in chlorinated water for extended periods after use.
