Packing outdoor swimming gear for a family holiday is trickier than it should be. Sun protection, swim nappies, learn to swim aids, keeping little ones warm in the water: the list grows fast. And it's surprisingly easy to fill a suitcase with things you don't need and forget the stuff you do. This guide gives you a practical, age-by-age breakdown so you can pack with confidence and actually enjoy your time by the pool or at the beach. Our Holiday & Learn to Swim Bundles are a great place to start if you'd rather skip the guesswork altogether.
What specific features should you look for in outdoor swimming gear for kids?
Every child's different, so what you pack depends on their age, swimming ability and where you're heading. Here's what to think about before you start filling that suitcase.
Leak protection (babies and toddlers not yet potty trained)
A reusable swim nappy is a must. Most UK swim schools insist on them and many hotel pools abroad do too. You want a snug fit with secure seals around the thighs and waist to contain faecal leaks. The Happy Nappy™ does this with soft neoprene seals that sit comfortably against your baby's skin. For double layer protection, the Happy Nappy Duo™ features an active silver lining that kills germs within the nappy. Nothing needs to be worn underneath it, which makes it a much simpler option for holidays.
UV protection (all ages, outdoor swimming)
Little ones' skin is far more sensitive to UV radiation than ours. UPF 50+ fabric blocks over 98% of harmful rays and doesn't wash off the way sun cream does. Go for high necklines and coverage across shoulders, back and arms: these are the areas that burn fastest. Always apply sun cream to exposed skin such as the face, hands and feet.
Warmth (all ages)
Outdoor pools, UK beaches and early morning hotel pool sessions can be surprisingly chilly. Nobody wants swim time cut short by shivering. Neoprene traps a thin layer of water against the skin, which the body warms naturally. This keeps children comfortable for longer so everyone gets to enjoy the water.
Learn to swim support (ages 1 and up)
If your child's still building water confidence, a swim aid that holds them in a natural swimming position makes a real difference on holiday. It's brilliant for boosting their confidence in an unfamiliar pool. Adjustable systems let you reduce support as confidence grows. Non-removable flat floats are perfect for travel because they pack down into a suitcase without any fuss. All swimming aids must be used under constant adult supervision.
Packing and drying
Holiday gear needs to be lightweight. Quick-drying fabrics save space and mean you're not shoving damp swimwear into bags at the end of the day. Flat-packing designs are your friend here.
How do outdoor swimming products for children compare in direct comparisons?
Swim nappies: The key difference is layers of protection. The Happy Nappy™ provides reliable faecal leak protection with its signature neoprene seals. It's the go-to for swim schools and pool sessions. The Happy Nappy Duo™ goes further with a double layer design and active silver technology that eliminates pathogens within the nappy itself. You don't need to put anything underneath it. For holidays, that simplicity is worth a lot: one less thing to think about when you're wrestling a wriggly toddler poolside.
Keeping warm: The Baby Wrap™ and the Warm In One™ do different jobs, so which one you choose depends on what matters most to you. The Baby Wrap™ is a 2 mm neoprene wetsuit suitable for babies aged 0 to 30 months. It covers the core of the body, leaving arms and legs free to kick, splash and feel the water. Its velcro fastenings open completely flat, which makes changing quick and easy: a real lifesaver during busy swim class sessions. The Warm In One™ is our warmest baby wetsuit. It uses TPU with a polyester fleece lining rather than neoprene, giving full body coverage including arms and legs. If your baby feels the cold in the water, the Warm In One™ is the better pick for keeping them cosy and happy for longer.
Learn to swim products: Watching your child grow in water confidence is one of the best parts of family swimming. Floatsuits (suitable for ages 1 to 6) have a 16-piece adjustable float system. You remove floats in pairs as your child gets more confident, so they last a long time. The Go Splash Swim Vest takes a different approach. Its non-removable flat floats make it lighter and more compact: perfect for squeezing into a suitcase. Heading on a pool holiday and need something that packs small? The Go Splash Swim Vest is the one. Want something your child can grow with over months of swimming development? Go for the Floatsuit.
Sun protection: Rash vests cover the torso with UPF 50+ fabric and layer easily over swim nappies or swimwear. The UV Sun & Sea Wetsuit gives you full body coverage using 1 mm neoprene combined with polyester/elastane panels. It protects from sun, wind and sand on the beach, and it keeps children warm in the water too. The Sleeved Floatsuit pairs sun, wind and sand protection with integrated learn to swim floats: so that's two jobs done in one piece.
Which outdoor swimming essentials are best for different holiday scenarios?
Beach holidays abroad (warm climate)
Sun protection comes first. Pack a UV Sun & Sea Wetsuit or rash vest with UPF 50+ coverage, a legionnaire hat to shield the neck and ears and sun cream for exposed skin. If your child isn't potty trained, the Happy Nappy Duo™ keeps things simple: no fiddling with separate layers. For children aged 1 and over who are still building confidence, a Go Splash Swim Vest packs flat and supports them in the correct swimming position in the hotel pool. All swimming aids must be used under constant adult supervision.
UK staycations and outdoor lidos
Warmth matters more here, and the British weather can be unpredictable even in summer. For babies who feel the cold, the Warm In One™ is our warmest option with its fleece lining and full body coverage. The Baby Wrap™ (for babies aged 0 to 30 months) is a great choice for swim classes and pool sessions where easy changing is a priority. For older children, a Shorty Wetsuit will keep them comfortable in cooler water. Layer a rash vest underneath on breezy days. And don't underestimate the British sun: UV protection is still essential on overcast days because UV rays penetrate cloud cover.
Holiday park and resort pools
These tend to be heated, so you can keep things nice and simple. A Happy Nappy™ or Happy Nappy Duo™ paired with a swimming costume works really well. For older toddlers, Splash Jammers™ provide leak protection in a more grown-up swim shorts design and can be worn on their own without a separate nappy underneath. If the pool area has lots of outdoor space, a legionnaire hat and rash vest will protect your child between swims. Pack goggles too: older children will want them for underwater games and you'll thank yourself later.
Camping and paddling pool days
Keep it simple. The Happy Nappy™ Sunsuit combines a UPF 50+ rash top with integrated Happy Nappy™ leak protection in one piece. It's perfect for paddling pools in the garden or splashing around at the campsite. Pair it with a legionnaire hat and apply sun cream to any exposed skin.
What are the best alternatives to standard kids' outdoor swimming gear?
Sometimes fewer items in the bag is the goal. We get it: suitcase space is precious. Combination products can help with that.
The Happy Nappy Costume™ builds Happy Nappy™ leak protection into a swimsuit, so that's one less thing to pack. The Happy Nappy™ Sunsuit pairs UPF 50+ sun protection with an integrated swim nappy: ideal for outdoor sessions where you need both covered.
If you'd rather avoid a full wetsuit for sun protection, rash vests are lighter and more flexible. They offer UPF 50+ coverage across the torso without the snugness of neoprene. Long sleeve versions cover more skin. Short sleeve versions let your child move more freely. Both dry quickly and layer well over swim nappies or swimwear.
Want to cut your packing list down even further? Consider a Floatsuit or Sleeved Floatsuit. These combine swimwear with integrated learn to swim floats in one piece. The Sleeved Floatsuit adds coverage across the arms, legs, shoulders and neck for protection from sun, wind and sand: fewer items, more covered. All swimming aids must be used under constant adult supervision.
For older children who don't need swim nappies but want warmth in cooler outdoor water, a Shorty Wetsuit works well. Made from 2 mm neoprene with 3/4 length arms and legs, it keeps children warm without restricting movement. It's also great for beach activities like watersports and rock pooling.
