Honest review of Gro Company sleep bags for Australian parents
When our third baby arrived last spring in Melbourne, we quickly realised how unpredictable Australian weather can be for little sleepers. One week it's a balmy 28°C night and the next there's a cold snap rolling in from the bay. Finding a sleep bag that works across these shifting temperatures became a small obsession. After late-night scrolls through Baby Bunting, we ended up with two Gro Company sleep bags and put them through the wringer for several months.
Gro Company has built a solid reputation in the UK for baby sleep solutions, and their Grobag range has been on the radar of Australian parents for years. We wanted to see whether the hype held up in our climate, with our washing machine, and against the strict safe-sleeping guidelines promoted by organisations like Red Nose. Here's what we found after roughly 400 nights of use.
This isn't a sponsored piece, and we paid full price for both bags. We're sharing the wins, the niggles, and what we wish we'd known earlier.

Why we picked Gro Company in the first place
Our eldest two were swaddle monsters, and I remember dreading the transition out of a swaddle wrap. With baby number three, I wanted to skip that battle entirely and go straight to a sleep bag from around eight weeks. After asking around on Australian parenting forums, the Gro Company name kept surfacing. Friends in Sydney swore by them, suggesting they weren't a fly-by-night product.
The other big draw was the variety of tog ratings on offer. Unlike some brands that only stock one or two weights, Gro Company offers 0.5, 1.0, 2.5, and 3.5 tog options. That meant we could match the bag to the room temperature, rather than guessing whether our little one was too warm or too chilly. In a country where summer nights in Brisbane can feel like a sauna and Adelaide mornings can be genuinely cold, that flexibility felt essential.
Sizing, tog ratings, and what works for Australian seasons
Sizing was the first hurdle. The bags come in sizes from 0–6 months through to 18–36 months, but the actual weight range matters more than the age guide. Our 10-week-old was on the smaller side and swam in the 0–6 month bag initially, though the adjustable poppers on the shoulders helped cinch things in. By four months, it fit beautifully.
The tog question took a bit of trial and error. We started with a 2.5 tog during a mild Melbourne autumn and quickly learned that our daughter ran hot. We swapped to a 1.0 tog and noticed fewer sweaty wakes. During the height of summer, the 0.5 tog was perfect paired with a short-sleeve bodysuit. Here's a quick breakdown of how the weights stacked up in our home:
| Room temperature | Tog rating | What we layered underneath |
|---|---|---|
| 24°C and above | 0.5 tog | Short-sleeve bodysuit only |
| 20–24°C | 1.0 tog | Long-sleeve bodysuit |
| 16–20°C | 2.5 tog | Long-sleeve bodysuit + sleepsuit |
| Below 16°C | 3.5 tog | Long-sleeve bodysuit + sleepsuit |
These are personal findings rather than hard rules, and Red Nose Australia provides excellent guidance on dressing babies for sleep based on room temperature.
Design details that actually matter at 3am
The features that matter most are the ones you notice when you're half asleep. The two-way zip on the Gro Company bags is a genuine lifesaver for night-time nappy changes. You can unzip from the bottom without fully exposing your baby's chest, which keeps them drowsy and avoids that full wake-up you desperately want to avoid.
We also appreciated the zip guard at the top, which prevents the metal puller from resting against baby's chin. The shoulder poppers are a small touch that made a big difference when our daughter decided to do her nightly stretch routine at 2am.
One minor gripe: the 0.5 tog bag is quite sheer, and the inner tag sits in an awkward spot right at the back of the neck. We ended up snipping it out, which I'd recommend doing carefully before first use.
Washing, durability and the test of time
Let's talk about the laundry side of things. Babies are messy, and sleep bags take a beating. We washed our Gro Company bags weekly, often at 40°C with a regular detergent, and they came out looking good as new. The colour didn't fade, the poppers didn't warp, and the zip still glides smoothly after dozens of cycles.
After six months of regular use, there's some very light pilling on the outside of our most-worn 2.5 tog bag, but nothing that affects function. We've tumble-dried on low a few times by accident and the shape held. The fabric still feels soft against delicate skin, and there are no loose threads or popped seams to report.
One thing worth noting: if you're buying second-hand or handing bags down between siblings, check the condition of the zip and the tog rating carefully. Sleep bags don't last forever, and the tog rating can become less accurate if the filling has compressed over time.
Safety, standards and peace of mind
Safety is non-negotiable when it comes to baby sleep products. In Australia, children's nightwear must meet the AS/NZS 1249 standard for reduced fire hazard, and Gro Company bags comply with this requirement. They're also designed to be used without additional blankets, which aligns with Red Nose Australia's safe sleeping guidelines recommending babies sleep with their face uncovered.
The bags have a fitted neck and armholes sized appropriately for each weight range, reducing the risk of a baby slipping down inside the bag. We always double-checked that the neck hole was snug without being restrictive. The zip opens downward, which prevents curious toddlers from unzipping themselves and using the bag as a play tunnel.
It's worth mentioning that sleep bags aren't suitable for every family situation. If your baby has certain medical conditions or mobility issues, chat with your paediatrician or child health nurse first. For typical healthy infants, though, we found the Gro Company bags offered reassuring safety credentials backed by clear labelling on the tog and size.
Value for money and where to shop in Australia
Gro Company sleep bags sit at the mid-to-premium end of the market. In Australia, you'll typically pay between $45 and $70 depending on the size and tog rating. That's more than the basics you'd find at Kmart or Big W, but the build quality and longevity justify the cost in our experience.
We've spotted them at Baby Bunting, selected Target Australia stores, and various online retailers. Shopping around pays off, as prices fluctuate between sales events. Keep an eye out for end-of-season clearances, particularly in late summer when retailers make room for winter stock.
If you're weighing up whether to invest, think of it this way: a bag used nightly for six months costs roughly 25 to 40 cents per night. That's less than a flat white from your local café, and your baby sleeps safely through it. We also found that the bags washed up well enough to hand down to friends, which spreads the value further.
