Kids' Swimwear Buying Guide: What to Look for in Fit, Fabric & UV Protection

Shopping for kids' swimwear can feel overwhelming with so many options available. But when you know what to look for, it becomes much easier. Here's our guide to finding the best swimwear for your little ones.

Prioritise UV Protection

Australia has some of the highest UV radiation levels in the world, so sun protection should be your number one priority. Look for swimwear with a UPF 50+ rating, which blocks over 98% of UV rays. Full-coverage styles like rash guards, swim shirts, and long-leg suits offer the best protection for extended time outdoors.

Choose the Right Fabric

Kids are tough on their gear, so durability matters. Look for chlorine-resistant fabrics if your child swims regularly in a pool. Polyester blends hold their shape and colour better than nylon over time. Avoid cotton — it absorbs water, becomes heavy, and dries slowly.

Getting the Fit Right

Swimwear that's too loose can cause drag in the water and may slip during active play. Too tight and it becomes uncomfortable quickly. Look for adjustable straps, elasticated waistbands, and size guides that account for height and weight rather than just age.

Style Considerations

Kids have opinions! Involving them in the choice — whether it's a favourite colour, character, or pattern — means they're more likely to wear it happily. For girls, rash guard sets and one-piece suits are practical and secure. For boys, rash guard tops paired with swim shorts are a classic combination.

Easy On, Easy Off

For younger children especially, consider how easy the swimwear is to get on and off — particularly for toilet breaks. Two-piece sets and shorts with elastic waistbands are much more practical than one-piece suits for toddlers.
