As recommended by most baby swim schools, including the ones run by Waterbabies who recommend using a Happy Nappy Wrap with liner underneath the Happy Nappy for best results. There is no need to use a disposable swim nappy if you use this combination. See here for more info.
They are made of 1mm supple, stretchy neoprene and finished with super
soft, snug fitting, deep bands of fabric with a high rubber content to
keep all nasties inside.
Designed by us with swim teachers, parents and babies in mind! So
simple and yet so effective, no ties, no Velcro, no elastic. IT WORKS!!
Can be worn with or without a conventional swim nappy - a liner is
advised for ease of cleaning. Tested and improved upon with the leading
UK swim teachers.
