Swim 101: How Much Skin *Should* a Racing Suit Cover?

[SSEditor]

TL;DR

• In pool racing, men’s suits go from **waist → knee**; women’s suits go from **shoulder → knee**, and must not cover neck.✅
• Suits that go above the navel (for men), past the shoulder (for women), or below the knee are illegal in most USA Swimming pool meets.❌
• Open water rules are different: suits may extend to the ankle, but still **cannot cover the neck or pass the shoulder**.🌊
• If you’re buying a suit, always check it matches what’s allowed for your swimmer’s gender, event (pool vs open water), and age. Coaches and hosts will check at the blocks.📏

How It Works

Here’s what the rules say about how much of the body a legal racing suit can cover in USA Swimming:

• For pool competition:

  • Men’s suits must not extend above the navel nor below the knee. oai_citation:0‡USA Swimming
  • Women’s suits must not cover the neck, extend past the shoulder, nor extend below the knee. oai_citation:1‡USA Swimming

• For open water racing:

  • Suits may go all the way to the ankle, but still may not cover the neck or extend past the shoulder. oai_citation:2‡USA Swimming

These rules help keep things fair (so gear can’t give someone an unfair hydrodynamic advantage) and consistent for all swimmers.

Real-Life Example

Imagine you have a 14-year-old boy who wants to wear a long-legged suit that reaches below the knees at a pool meet. The coach checks: is it just knit fabric with sewn seams, and is the bottom just at the knee? If it extends below the knee, it’s illegal for that pool meet—even if it “looks the same” as legal suits.

Or think about a woman racing in open water who picks a suit that covers her neck and arms. Even though it covers more skin (and might feel more comfortable), if the race rules say “no neck coverage” she may get a violation or be asked to change.

Special Notes

• “Covering the neck” means the fabric must stop below the base of the neck — no high collars.
• “Extending past the shoulder” means straps must not go over or wrap past the top of the shoulder.
• “Below the knee” means the bottom hem of the suit must sit at or above the knee (for most pool meets for both men and women).
• Suits must also be non-transparent. If you stretch the suit and it becomes see-through, that can be a problem. oai_citation:3‡USA Swimming
• If you are swimming both pool and open water, you may need two suits, because the allowed coverage may differ.

Quick Tips

• When shopping: have your swimmer try it on (in good lighting), stretch arms/legs to check coverage.
• Ask if the suit is “open-water legal” if you plan to swim open water—it helps avoid surprises.
• Keep spare options in case meet check-in or officials require you to change.
• Coaches/teams may maintain lists of approved styles to simplify decisions.
