If you've been searching for a baby zip onesie that ticks every box, from fabric quality to clever design to easy nappy access at 3am, you've landed in the right place. At Zoe Sage, we're an Australian baby and toddler brand built around one idea: that the everyday essentials your little one wears and uses should be genuinely good. Premium materials, thoughtful design, and nothing unnecessary. Our Bamboo Zip Growsuit Rompers are one of our most-loved pieces, and with free shipping available across Australia, getting them to your door has never been easier.
Why Bamboo Zip Onesies Are Worth It
Not all baby onesies are created equal. Bamboo fabric has earned its place in nurseries across Australia for good reason. It's incredibly soft against newborn and baby skin, naturally breathable, and moisture-wicking, which means it moves sweat away from your baby's body rather than trapping it. That's a big deal during those warm Australian summers, and just as useful in cooler months when layers can get a little stifling.
The zip closure is the other half of the equation. If you've ever wrestled with a row of popper buttons in the dark while holding a very unhappy baby, you'll understand why the zip design matters so much. A single, smooth zip from neck to toe means nappy changes take seconds, not minutes. Our zip pulls are also covered and gentle, so there's no cold metal against soft skin.
If you're weighing up whether a zip or button closure suits your family's routine, our detailed comparison in which closure makes night changes easier breaks it all down honestly, so you can make the choice that actually works for you.
Meet the Bamboo Zip Growsuit Romper Range
Our bamboo zip growsuit rompers come in five beautifully considered colours, each one designed to feel as good as it looks. These aren't the kind of shades that fade after a couple of washes either. Here's a closer look at each option.
Bamboo Zip Growsuit Romper, Grey Storm
A modern, cool-toned grey that works for any baby, any season. The Bamboo Zip Growsuit Romper, Grey Storm is a wardrobe staple that pairs with everything and photographs beautifully. If you're buying for a newborn and don't know the sex yet, or if you simply prefer a versatile neutral, this is the one.
Bamboo Zip Growsuit Romper, Cove Green
Earthy, calming, and a little unexpected. The Bamboo Zip Growsuit Romper, Cove Green draws on that soft, natural palette that's so popular in Australian nurseries right now. It works just as well on its own as it does layered under a little knit vest on a cooler morning.
Bamboo Zip Growsuit Romper, Taro Purple
A muted, dusty purple that sits beautifully in the botanical-meets-neutral space. The Bamboo Zip Growsuit Romper, Taro Purple is one of those shades that looks even better in person than it does on screen. Subtle, sophisticated, and completely gorgeous on babies of all skin tones.
Bamboo Zip Growsuit Romper, Twilight Pink
Not your average pink. The Bamboo Zip Growsuit Romper, Twilight Pink is soft and muted rather than bold, giving it a timeless quality that doesn't lean too sweet. It's a lovely choice for a newborn gift or a first birthday present, and it layers beautifully under our Cotton Classic Knit Baby Blanket for those cooler evenings.
Bamboo Zip Growsuit Romper, Horizon Blue
A quiet, sky-inspired blue that feels fresh without being loud. The Bamboo Zip Growsuit Romper, Horizon Blue is one of those colours that somehow works in every photo, every season. It's a solid choice if you want something that feels a little different from the usual pale blue options.
Designed for Real Life With a Baby
Good design is the difference between a piece of clothing you reach for constantly and one that sits in the drawer. Our Bamboo Zip Growsuit Rompers are cut with a generous fit so there's room for a nappy underneath without looking bulky. The fabric has a silky, smooth hand feel that stays that way after repeated washing. And the zip runs from the collar all the way to the bottom of one leg, making full access for nappy changes fast and fuss-free.
Safe sleep is something we take seriously at Zoe Sage. The Red Nose Australia safe sleeping guidelines recommend keeping baby's sleep environment simple and well-fitted clothing that doesn't bunch or ride up. Our growsuits are designed with this in mind: a snug but comfortable fit with no loose fabric, no hoods, and no excess material around the face or neck during sleep.
It's also worth thinking ahead as your baby grows. If you're curious about the longer picture, our guide on when babies typically move on from rompers is a helpful read for planning your wardrobe buys across the first year and beyond.
Bundle It Up: Pair Your Growsuit With These Essentials
One of the best things about shopping with Zoe Sage is that everything is designed to work together. If you're putting together a newborn wardrobe or a thoughtful baby gift, here are a few pieces that pair perfectly with the growsuit range.
After bath time, nothing beats wrapping your baby in one of our hooded towels. The Bear Hooded Baby Bath Towel & Mitt, Baloo and the Hooded Bamboo Baby Bath Towel & Mitt, Blanca The White Bunny are both made with the same attention to softness and quality. Pop a freshly bathed baby straight into a Bamboo Zip Growsuit Romper and you have the perfect end-of-day routine sorted.
For feeding times, our Linen Bandana Dribble Bib is a practical pick that doesn't look out of place over a beautiful growsuit. If you're looking for a complete set, the Linen Dribble Bib, Triple Bundle gives you a few on rotation, which is exactly what you need in those early months.
And if you're buying as a gift, our Mama Pregnancy Gift Box (Organic) and Grab & Go Mum Ready Duo Bundle are popular choices to pair alongside a growsuit for a complete, considered present. You can also add a Gift Voucher if you'd prefer the new parents to choose their own colour.

Frequently Asked Questions
What sizes do the Bamboo Zip Growsuit Rompers come in?
Our Bamboo Zip Growsuit Rompers are available in a range of sizes to suit newborns through to toddlers. Check the individual product pages for the full size guide, including chest and length measurements, so you can choose the best fit for your little one.
How do I care for bamboo onesies?
Bamboo fabric is easy to care for but does best with a gentle machine wash in cold or warm water. Avoid high heat in the dryer as it can affect the fabric's softness over time. Line drying or a low tumble dry setting will keep your growsuit looking and feeling great wash after wash.
Are the zip onesies safe for overnight sleep?
Yes. Our growsuits are designed with safe sleep in mind, featuring a well-fitted cut with no loose fabric. For broader guidance on safe infant sleep, the Red Nose Australia safe sleeping recommendations are the most up-to-date Australian resource. Always dress your baby in a way that suits the room temperature and follow the guidelines for their age and weight.
Can I buy the Bamboo Zip Growsuit Rompers as a gift?
Absolutely. They make a beautiful, practical gift for new parents. You can choose a single colour or pick up a couple in different sizes so the family has something to grow into. If you're unsure which colour to go with, a Gift Voucher lets the parents choose for themselves. Our packaging is neat and gift-ready, so no extra wrapping is needed on your end.
