One-Piece vs Two-Piece Swimwear for Kids: Which is Better?

When it comes to getting your little one swim-ready, one of the first decisions you'll face is: one-piece or two-piece? Both have their place, but depending on your child's age, activity level and sun exposure, one option might work way better than the other.

The Case for One-Piece Swimwear

If sun protection is your top priority (and let's be honest, in Australia it should be), a one-piece is hard to beat. More fabric means more coverage, which means less sunscreen stress for you and less burn risk for them.

One-piece styles like our shortie swimsuits offer UPF50+ protection from shoulders to thighs. No riding up, no exposed tummies, no gaps between top and bottom. Just zip and go.

For babies and toddlers still in nappies, look for one-pieces with snap closures at the crotch. This is a game changer - you can do a full nappy change without stripping the whole suit off. Trust us, poolside nappy changes just got a whole lot easier.

The Case for Two-Piece Sets

Two-piece rashie and shorts sets are brilliant for older kids who are in and out of the water all day. They're easier for toilet trips (no full undressing needed), and you can mix and match sizes if your child is between sizes on top and bottom.

Rashie tops also double as great sun protection shirts for playing on the beach or in the park, even when swimming isn't on the agenda.

What About Sun Protection?

Whether you go one-piece or two-piece, always look for UPF50+ rated fabric. This blocks 98% of UV radiation and is your best defence against sunburn. Pair it with a hat, sunnies and sunscreen on exposed skin and you're set.

At Pekpi, all of our swimwear is UPF50+ rated and made from recycled nylon. Because protecting your kids and the planet shouldn't be an either/or situation.

Our Pick?

For babies and toddlers (0-2): one-piece shortie with snaps. Maximum coverage, minimum fuss.

For bigger kids (3+): either works great. Let your child's preference guide you.

For all ages: make sure it's UPF50+ and made from quality fabric that won't fade or stretch after a few wears.
