Frequently asked questions

Which pool swimsuit should I pick for a boy?

The H2Otto boys' swim briefs: the same training briefs the grown-ups wear, in Speed Line 100% PBT polyester, with prints such as Papere righe, Bradipo, Ciliegie or Camouflage.

Will they stand up to swimming-lesson chlorine?

Yes: with no elastane, PBT resists chlorine, keeps its shape and does not fade. After the pool, just rinse in cold water and leave to air-dry, no washing machine.

What size for a 10-year-old?

Build matters more than age: training briefs should fit close. Email info@boneswimmer.it with height, weight and usual size and customer service will suggest the right one.

Boys' training swimwear

Boys' training swimwear. The boys' training line is built around the H2OTTO swim brief: simple, quick to put on and made for regular pool sessions.
