Girls Speedo Swimwear

Speedo is the swimsuit most Australian girls learn to swim in, and the one most squads still recommend. This range covers girls' Speedo swimwear from toddler sizes through to junior squad, with the majority built in Endurance+ — the fabric that made Speedo the default choice for pool swimming.

Why Endurance+ matters for a girls' swimsuit

Most girls' swimwear fails the same way: it goes baggy in the seat, the straps stretch, and the colour fades until it's see-through. That's chlorine breaking down the elastane in the fabric. Speedo's Endurance+ is 53% polyester and 47% PBT polyester with no elastane for chlorine to attack — Speedo rates it 100% chlorine resistant and twenty times more fade resistant than conventional swimwear, with four-way stretch so it still moves. For a girl swimming three or more times a week, it's the difference between one suit a season and one suit a term. There's more detail in our swimwear fabrics guide.

Choosing the right style

One pieces make up most of this range — Medalist, Powerback, Lane Line Back, Flyback and Allover V Back. These are the everyday squad and lesson suits: full coverage, secure straps, nothing to adjust mid-lap. If you're buying one suit, buy one of these.

Legsuits and kneelength add leg coverage, which some girls prefer for comfort and sun protection during outdoor sessions.

Sun tops pair with a one piece for outdoor pools and open water, and are worth having through a Queensland summer.

Toddler styles are cut for learn-to-swim — easy on and off, secure straps, and built to survive warm teaching pools, which are harder on fabric than any squad pool.

If she's racing rather than training, competition suits are a different thing entirely — see Girls' World Aquatics approved racesuits.

Getting the size right

Girls' swimwear should feel firm when new — a suit that fits comfortably on day one will be loose within a month. Size to current measurements rather than buying ahead; chlorine-resistant fabric doesn't stretch to fit the way elastane blends do. Our size charts cover every brand we stock, and our Woolloongabba team are happy to help if you're between sizes.
