Frequently asked questions

What swimwear is there for kids?

For the pool: Pinup for girls and H2Otto swim briefs for boys, the same training models the grown-ups wear. For the beach and holidays: the Alte one-piece and Waikiki bikini for girls, Samoa swim shorts and Tobago square-leg trunks for boys.

Does a swimming course need a training swimsuit?

Yes. For lessons pick a training model, Pinup or H2Otto: elastane-free PBT, chlorine-resistant, holds its shape and colour. Alte, Waikiki, Samoa and Tobago are made for holidays, the beach and splashing about.

Are there matching swimsuits for parents and kids?

Yes, many prints come in adult and kids' sizes: for example Porky's, Psycho and Zitto e Nuota on Pinup and H2Otto, Use Your Smile on the women's Dega one-piece and on Alte for girls.

What size should I get for a child?

A training swimsuit should fit snugly; for beachwear go with the usual size. If in doubt, email info@boneswimmer.it with height, weight and usual size: customer service will suggest the model and size.

Kids' swimwear

Kids' swimwear. Kids' training swimwear and beachwear, kept simple: girls and boys, pool and beach, sorted the same way as our adult lines.
