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.
