What you actually need
A training suit is the starting point. A basic nylon one-piece works for any kid under 12. Only jump to a competition tech suit if your child is 12 or older and swimming competitively year-round. The performance gains are real at that level, but younger swimmers don’t need it.
Goggles with anti-fog coating make the difference between liking and hating practice. Get something decent here, bargain-bin goggles fog constantly and kill enthusiasm. A swim cap keeps hair out of the way and is practically free. A good towel is mandatory, but any standard bath towel works fine.
That’s it. Four items. This is the cheapest sport to get started in.

Youth competitive training swimsuit
Basic nylon or polyester training suit in youth sizing. Holds shape through a full season of daily practice. Not a tech suit — the right call for any swimmer under 12 or any recreational swimmer.
Our take: One suit is enough for most kids. Buy two if your kid is in the water six days a week. Confirm with your team whether they specify a required color or brand.

Silicone swim cap — youth
Unisex silicone cap in youth sizing. Keeps hair out of the face and out of the water. More durable than latex and easier to put on.
Our take: Most teams require a cap. Used caps are fine; new ones are a few dollars. Keep a spare in the bag — they tear at the worst moment.

Speedo Hydrospex kids goggles
Speedo's kid-sized goggle with anti-fog lenses, UV protection, and a soft silicone frame. Sized for ages 6 to 14.
Our take: Goggles are the one swim purchase worth doing right, and they're the one you always buy new. Foggy goggles end swim careers faster than cold pools.

Used gear notes
Used suits and caps are fine from Facebook Marketplace or Play It Again Sports. Goggles should be new, used ones have scratches and dead seals that defeat the whole purpose. Always buy new.
What you can skip
Skip tech suits until your child is older and committed. Skip the fancy warm-up jacket, a regular sweatshirt works. Skip multiple caps. One is plenty. Skip the equipment bag. A grocery bag works fine.
