Planning a trip to the pool or beach with your baby? Choosing the right swimwear might seem simple at first, but when it comes to your little one, the right swimsuit can make all the difference. From comfort and protection to hygiene and warmth, the features of your baby’s swimwear should work together to ensure a safe and happy water experience.
With a wide variety of options available, knowing what to look for can be overwhelming. That’s why we’ve put together this practical guide to the top features to look for in baby swimwear—plus some standout picks from the trusted baby swimwear collection at Splash About, a go-to brand for parents worldwide.
- Leak-Proof Design Is a Must
The number one priority in baby swimwear is preventing accidents in the water. No one wants to be that parent whose baby has a bathroom mishap in the pool. That’s why high-quality swimwear should feature a built-in swim diaper or leak-resistant design.
One of the best options on the market is the Happy Nappy from Splash About. This reusable swim diaper is loved by parents and approved by swim schools around the world. It features soft neoprene material with a snug fit at the waist and legs, which gently seals in any mess without causing irritation. Not only does this help keep pools clean, but it also saves you from relying on disposable swim nappies.
- UPF Protection for Delicate Skin
Your baby’s skin is highly sensitive to the sun, and traditional sunscreen isn’t always ideal—especially for babies under six months. That’s why swimwear with built-in UV protection is an essential feature.
Look for swimsuits labeled UPF 50+, which block 98% of the sun’s harmful rays. Full-coverage suits, like rash tops or sunsuits, are excellent choices for minimizing sun exposure while letting your baby splash around freely.
The UV Sun & Sea Wetsuit from Splash About not only offers full-body sun protection but also keeps your little one warm in cooler water. This dual function makes it a great option for both outdoor beach days and indoor pool sessions.
- Comfortable, Snug Fit Without Tightness
Babies can be fussy, especially when something doesn’t feel right. Swimwear should feel like a second skin—snug enough to stay in place and provide protection, yet soft and flexible enough to allow natural movement.
Avoid anything with stiff seams, tight elastic, or tags that can rub against delicate skin. Splash About’s swimsuits are crafted with baby comfort in mind, using flat-lock seams, stretchy neoprene, and soft linings that feel gentle even on sensitive skin. Their Happy Nappy Wetsuit, for example, combines the famous leak-proof diaper design with a cozy, fleece-lined neoprene body for maximum warmth and comfort.
- Easy On, Easy Off
If you’ve ever tried to wrangle a wet swimsuit off a wiggly baby, you know how important easy changing features are. Swimwear with wide openings, adjustable closures, or zip backs can make all the difference in a smooth changing experience.
The Baby Wrap Wetsuit from Splash About is a standout in this area. Made with Velcro fastenings at the shoulders and chest, it opens up completely flat, so you can easily lay your baby down, wrap them up, and go. Taking it off is just as hassle-free, especially when your baby is wet, tired, or both.
- Thermal Protection for Warmer Swims
Babies lose heat much faster than adults, and cold water can lead to discomfort or even hypothermia. That’s why swimwear with thermal insulation is an excellent investment, especially if you’re planning frequent trips to the pool.
The Warm In One Wetsuit is a parent favorite for this very reason. With its fleece-lined, long-sleeved design, it keeps your baby snug and warm for longer swimming sessions—even in cooler water environments. This added warmth can also reduce the number of breaks needed during swim lessons or playtime.
- Reusable and Eco-Friendly Materials
Sustainability is becoming increasingly important to modern parents. Reusable swim nappies and eco-conscious fabrics are a great way to reduce your environmental impact while still getting the features you need.
Splash About’s reusable Happy Nappy system helps cut down on waste from disposable diapers, and their swimwear is built to last, even after dozens of uses. Not only is this better for the planet, but it’s also easier on your wallet in the long run.
- Stylish and Practical Designs
While function should always come first, no one said baby swimwear can’t be cute too! Fun prints, bright colors, and charming designs are just the cherry on top. But beyond the aesthetics, practical design elements—like longer leg coverage, neck protection, or matching sun hats—can add real value.
Splash About offers a variety of coordinated sets, including swimsuits, rash tops, and sun hats in matching prints. This helps you stay stylish while still providing full coverage and functionality.
- Approved by Swim Schools
Many swim schools have specific requirements for what babies can wear in the water. Choosing a swimsuit that’s swim school approved not only ensures a smoother lesson experience but also gives you peace of mind that the product meets hygiene and safety standards.
The Happy Nappy is often required by swim instructors, and it has become the gold standard in baby swimwear for structured lessons. Its reliability and tested design make it a must-have for parents starting their baby’s swimming journey.
