This versatile, super soft and incredibly warm thermal all in one, is the perfect solution for keeping babies cosy whilst in the water.

Designed to fit closely and move with your baby, the Thermaswim Babysuit features a brushed fleece inner, which will keep baby feeling snug and warm during their swimming session. Long, hemmed sleeves and legs provide maximum coverage, whilst the full length zip and super stretchy material helps make changing easier, even when the suit is wet.

These soft, comfortable fleecy suits can be worn alone as a swimsuit, or as a base layer under clothing in chilly weather, as they are suitable in both wet and dry environments! Please note however, they are not designed to be used in hydropools or those heated above 32°C due to a risk of overheating.

There is no need to wear any other baby wetsuit underneath the Thermaswim Baby Suit, as it is designed to provide enough warmth for an indoor pool for baby swimming session.

Remember that your little one will need to wear a Happy Nappy DUO or Happy Nappy and nappy wrap or under nappy underneath the Thermaswim suit during your Water Babies lessons, to conform with the Double Nappy System.

Good but a double zip would be more practical

Please consider making the zip a double zip, so that baby can be changed from the legs up whilst the top is still covered up.

Mixed feelings

A warm suit that is easy to get on your baby which is great and makes for a comfortable change before / after swimming. However, I have only washed this once and it’s already bobbled all over reducing the quality of the appearance.

Best thermal suit

I am so impressed with how much easier this suit is to put on than the neoprene models. It really is soft and stretchy. It keeps my baby warm for at least half an hour in a 29.7 degree swimming pool (leisure centre) and looks really cute. The front zip is so much better than a back zip and the material feels really nice.

Claudia Andrei

Good quality,soft and warm..My baby doesnt feel cold in the swimming pool anymore

Cosy and warm

Very soft, cosy and warm - really helpful for our baby in the pool. Love the fact that it can be worn outside the water as well when it is dry 👍
