Most product stories begin with "we wanted to design the most beautiful…" Ours starts somewhere a bit less glamorous: a public pool change room, a soaking-wet toddler, a swim nappy that needed urgent attention, and a one-piece swimsuit that we — past us — were trying to peel over the kid's head while the kid screamed.
Out of that exact moment, multiplied across three founders and approximately seven hundred similar moments, came the question: why does kids' swimwear open at the top?
Zips at the top: a design choice no one really questioned
If you look at most kids' one-piece swimwear, the zip — if there even is one — runs along the back or down the front from the neck. It's a hand-me-down convention from adult swimsuits. And for adults, who can step out of their swimwear without help, that's fine.
For kids, it's a small disaster. To do a nappy change, you have to peel a wet, sticky suit completely off a wriggling baby. Wet fabric grips skin like cling film. Toddlers don't sit still. The whole thing is a wrestling match. By the time you've done it, you've also somehow soaked yourself.
The leg-seam idea
Our zip runs along the inside leg seam, opening from the leg up to about halfway. Which means: instead of pulling the whole suit off, you unzip halfway, slip one leg out, change the nappy or do the toilet trip, and zip back up.
It sounds absurdly simple. That's because it is. The hard part wasn't the concept — it was the engineering. The zip needed to be:
- Soft enough to lie flat against a baby's leg without leaving a mark
- Tough enough to handle chlorine, salt and the washing machine
- Hidden enough that it didn't ruin the look of the suit
- Easy enough that one tired hand could operate it
It took multiple prototypes, a lot of poolside testing on actual babies, and several sessions where one of us would sit there opening and closing the zip for half an hour to make sure it didn't catch.
Why it actually matters
Quick maths. The average baby has 6–8 nappy changes a day. On a swim day, at least two of those happen while the kid is in their swimwear. Without a leg zip, that's two full undress-and-redress cycles. With it, it's two thirty-second jobs.
Multiply that across the dozens of swim days a baby has across a single Aussie summer and you've genuinely saved a parent hours of effort. We didn't appreciate quite how much until customers started telling us they timed it.
The unexpected wins
Some things came out of the leg zip we didn't see coming. Older kids — particularly preschoolers who toilet-trained mid-summer — suddenly had a swimsuit that didn't trap them when they needed to wee. No more frantic ten-minute wrestling match in the pool change room while the queue grows.
Kids with sensory sensitivities have been another one. A few mums have written in to say the leg zip is the only swimsuit their child will tolerate, because nothing has to come over the head.
And — small but real — it makes hand-me-downs work better. A Toggie that survived the eldest still has its zip, its stretch, and its colour by the time it gets to the youngest.
Small detail. Big difference.
It's the only design choice we'd never compromise on. Even when factories asked if it was easier to skip. Even when it added cost. Even when we had to redo it three times to get the leg lay right.
Because the whole reason Tini Togs exists is to make the small daily moments of being a mum genuinely easier. And nothing does that quite like a zip you didn't even know you needed, until suddenly it's there, and you wonder how everyone else is still doing it the old way.
