Quick Guide

Happy Nappy swimming costume with built-in reusable swim nappy

The Happy Nappy Costume combines all the safety features of the Happy Nappy and the cute styling of a girls swimming costume. 

Recommended and insisted upon by UK Swim Schools, our neo nappy, the Happy Nappy, is the most essential item in your baby swim kit. Made of 1mm premium quality neoprene and finished with snug fitting, deep bands of fabric with a high rubber content (to keep all nasties inside and ensure a leak-free swim); The Happy Nappy can be worn with or without a disposable swim nappy (though a liner is advised for cleaning). Better still, care of your Happy Nappy couldn't be simpler: after use simply Rinse, Roll and Reuse!
