This seriously cute Happy Nappy costume combines all the benefits of a Happy Nappy in a swimming costume – no need to wear a separate Happy Nappy underneath!* Made from a super-soft, stretchy nylon lycra for fuss-free changing, the exclusive eye-catching Bubba print means that your little one can swim in style - while you relax in the knowledge that any little accidents will stay safely inside. 

UPF 50+ sun protection.

* You will still need to use a disposable paper or reusable swim nappy with this product - All babies and toddlers need to wear a double nappy system in Water Babies lessons.

Lovely costume

Very pretty pattern and good strong material and very well made, everything feels like excellent quality.
Quick delivery too.

Lovely bright baby swim costume. Good quality and my 10 month old granddaughter is very happy wearing it when she’s in the pool.

Nice suit

My 7 month baby is nice and chunky so we upsized (to accommodate her thighs!), but that meant the body would be longer than needed. Despite this, it fits better than expected as it's stretchy so it's not too baggy on the top at all

Really good quality

Great product

Second product bought for my little girls swimming and both are excellent quality. Fairly easy to put on and we love the bold patterns.

The costume is so pretty and a great fit (I sized it off the chart) had it checked by the instructor who said it fit and still had some growing room which is great. Highly recommend
