Save Money
A reusable swim diaper is half the cost per wear of a disposable swim diaper:

   Using a reusable diaper for swimming lessons alone will save you $26 per year

  • Pack Lighter for Holidays

The Happy Nappy™ swim diaper weighs just 60g, thats 94% less than 2 packs of disposables

Save even more space in your suitcase with Happy Nappy™ swimsuits and sunsuits with integrated reusable swimming diapers.

Help the environment

Disposable swim diapers:

Going solely by the number of baby swimmers, reported by the 206 respondents to a 2014 survey by the Swimming Teachers’ Association, * a minimum of 943.8cm3 of (non-swelling) swim diapers are used in the UK each year, which is the equivalent of:

22.5 learner pools

Baby swimming lessons last only 30mins - thats 500 years in landfill for a product that's been used for just half an hour!

Extra comfortable

  • Soft material is gentle on sensitive skin
  • Integrated UPF protection


Leak-free swimming

  • Neoprene swim diapers provide a snug fit with tummy and thigh cuffs that protect against fecal leaks
  • Easy to clean and care for
  • Can be worn for a whole day at the beach for children who are nearly potty trained
  • Range of stylish designs - boys, girls and unisex
  • Suitable from newborns to older children, teenagers and adults

Reusable swim diapers are very easy to use – we always recommend rinsing our Happy Nappy swim diaper in cool water and leaving to dry away from direct sunlight. However, if the diaper is heavily soiled, we suggest a cool machine wash with non-biological detergent. Regular machine washing may affect the benefits the Happy Nappy provides. Read more here
