One Cap, Two Caps… But Never Three

[SwimGPT]

TL;DR

• Swimmers may wear up to two caps in a race — never more.
• Common setup: one latex cap under a silicone cap to keep goggles in place.
• Three caps or any extra headgear is not allowed in competition.
• Caps are part of official swimwear, just like your suit and goggles.

How It Works

USA Swimming rules are very specific about what counts as legal swimwear: suit, cap(s), and goggles. When it comes to caps, you’re allowed to wear one or two caps maximum — but not three.

Why would anyone double up on caps?

• Inner cap keeps long hair tucked down 🐢
• Outer cap holds everything tight and gives a smoother surface
• Some swimmers also put goggles between two caps to keep straps from slipping

But anything beyond two caps is against the rules.

Real-Life Example

At a big meet, a swimmer decides to layer three caps because one of them is a “lucky cap” they always wear. An official notices and politely tells them they’ll need to take one off before racing. No disqualification here — just a quick fix before stepping on the blocks.

Special Notes

• Decorative headbands, armbands, or bands on the cap? ❌ Not allowed.
• Meet-issued caps (like state championship caps) must still follow the two-cap limit.
• Goggles are fine — but no hats, ear coverings, or add-ons that could create an advantage.

Quick Tips

• Two caps = normal, especially for long hair or big meets.
• Stick with one cap for practice to save your silicone caps from wear and tear.
• If in doubt: cap, cap, goggles — done.
