    TL;DR
    • In 2008–2009, swimmers wearing full-body polyurethane “super suits” smashed world records.
    • These suits added buoyancy and reduced drag — giving unfair advantages.
    • USA Swimming (and World Aquatics) now require suits to be made of textile material only.
    • Today’s rule: men’s suits = waist to knee; women’s suits = shoulder straps to knee. Suits must be textile, non-transparent, and appropriate.

    How It Works

    Before 2010, swimsuit technology exploded. Companies built full-body suits from materials like polyurethane, which trapped air, increased buoyancy, and dramatically reduced drag.

    The results? In just two years, nearly 200 world records were broken. 🏊‍♂️ Times dropped so fast that it was clear athletes weren’t just racing — their suits were doing part of the work.

    To protect the integrity of the sport, USA Swimming and World Aquatics banned those suits. From then on, competition swimwear had to be:

    • Textile only (knit or woven fabric, no polyurethane panels)
    • Form-fitting but not performance-enhancing
    • Coverage-limited (men: waist–knee, women: shoulder–knee)

    Real-Life Example

    Imagine showing up to a meet in 2025 with a shiny, plastic-feeling “retro” LZR Racer super suit. It might look cool, but it’s not legal. Officials would immediately flag it for being non-textile.

    On the other hand, if you wear a modern “racing suit” made of woven or knit fabric, even if it feels high-tech, it’s legal as long as it meets textile standards.

    Special Notes

    • Textile means fabric with fibers woven or knitted together — not solid sheets of material.
    • Even approved suits can’t be transparent or extend beyond allowed coverage zones.
    • Open water racing has slightly different coverage rules (ankle-length allowed, but still textile only).
    • The ban wasn’t about stopping innovation entirely — it was about keeping the race about the swimmer, not their gear.

    Quick Tips

    • If the suit feels more like plastic than fabric, it’s not legal.
    • Check for a World Aquatics approval mark/tag on racing suits.
    • Don’t assume “expensive = legal” — always double-check fabric and coverage rules.
    • Save the history lesson: today’s world records are still compared to the “super suit era” of 2008–2009.
