Thermaswim Baby & Toddler Suits
If your baby has ever come out of the pool shivering, you'll know how quickly the cold sets in, and how hard it is to get them happy again. Our Baby and Toddler Thermaswim suits are brushed fleece thermal swimwear that keeps little ones warm and comfortable in the pool or open water. We make two cuts: the Thermaswim Baby Suit and the Thermaswim Toddler Suit.
Choosing the Right Thermaswim Suit
Babies grow fast, so we've cut each suit for a different stage:
-
Baby Suit: 3 months to 2 years, with full-length sleeves and legs, plus a zip to make changing a wriggly baby quicker
-
Toddler Suit: 2 to 6 years, knee length with 3/4 sleeves, so busy toddlers can move freely
Both suits are 95% polyester and 5% spandex. Neither has a built-in diaper, so pop a Happy Nappy™ swim diaper on underneath for the pool.

They can, in a very warm pool. Thermaswim is made for cooler water. If your pool runs warmer than 90°F (32°C), leave the suit at home, because your baby could overheat. In cooler pools and open water, it'll help keep them comfortable for longer.
