Customer Reviews:
The easy to use double-ended zipper means you can do night nappy changes without taking the whole suit off.
At The Sleep Store, we love to find amazing products that help children sleep better. We've hunted the world for a really warm, safe, versatile sleepsuit for kids and never found something we really loved.
So we've developed our own Sleep Store Merino Fleece Onesie. Our kids love it so much they refuse to take them off in the morning. We've tested them on very chilly nights camping and in comfy cosy beds at home. Big thumbs up all round.
This snuggly Onesie is designed for sleep! It's warm enough for kids who kick off their covers, so they won't wake up cold. And it's also perfect for using with one of our Sleep Store merino duvets or some light blankets for those children who manage to keep their bedding on or who prefer to layer up. And definitely cosy enough for children like our third, who is very skinny and really feels the cold, so he loves this onesie with a duvet on top.
Lots of customers also report these are amazing inside a sleeping bag! Layer with a mid-weight bag such as a 3-seasons woolbabe or our 1 layer merino bag.
Merino is naturally temperature regulating, so the onesie helps your child to be just the right temperature all night.
Plus we also love that merino is naturally fire retardant. Of course we recommend keeping your children well away from any heaters and fires ("a metre from the heater!") but merino is a naturally low fire danger fabric.
The Sleep Store Onesie is made from a soft, snuggly one layer of 100% merino fleece. So its soft brushed finish on the inside feels divine against the skin.
We're also delighted to have worked very closely with the amazing owner and designer of Babu, Ali Hui, who has helped us develop this wonderful Onesie. Ali has many years of expertise, so our manufacturing and design has been in very capable hands. Ali has worked for over a year developing this amazingly soft and warm fabric for us - we hope you'll love it as much as do.

Fabric:
100% merino fleece - 290 grams
Care for your merino fleece onesie:
As with all Sleep Store products, your onesie is easy to care for. We only develop products that are easy for parents!!!
Gentle machine wash with wool detergent. You can low tumble dry if you really need to, but hot tumble drying will result in shrinkage. So we recommend drying on an airing rack, heated towel rail or on the line. The fleece dries amazingly quickly.
As with many wool garments, you may experience a bit of pilling on this garment. Please note this is often due to a soft fibre such as merino rubbing against other fabrics, such as flannelette sheets. We consider pilling a normal part of wear and tear on a soft merino garment. We could have treated the fabric much more to reduce pilling but then it would lose its lovely, snuggly softness.
Please note these are a night time garment, designed for use in bed.Your child may love their onesie and end up in it all day, crawling round the floor. However please note that our returns policy does not cover worn out knees from crawling!
Fire Labelling:
CAUTION: KEEP AWAY FROM HEAT AND FLAME

Toddler doesn't want to take it off!
By Sarah (staff) from Auckland on 20 September 2019
Our toddler wears this to bed when he doesn't want to be in his sleeping bag. I know he's going to be cosy and warm all night and it layers so well. It's super soft and dries really quickly. The only problem is taking it off in the morning, our toddler wants to keep it on!!!
Lovely and warm
By Louise from Rotorua on 30 August 2019
Mr 8 absolutely loves his onesie! Fantastic quality, highly recommend - my son never wants to take his off!! Lovely and warm perfect for these cold nights
Gorgeous sleepsuit
By Jenna from Lower Hutt on 30 August 2019
When this order arrived I was beyond pleased. Such high quality merino and so thick. My babe loves her new sleepsuit (so much it’s difficult to pry her out of it in the morning hehe!) and it keeps her extra warm in these Wellington winter evenings.
Best merino ever!
By Emma Jane from Canterbury on 30 August 2019
This merino fleece zip suit is the most soft lush merino I’ve ever touched.
The outside is super soft and fine and the inside is fluffy and plush feeling.
It definitely keeps our boys toasty warm even out of the blankets.
The sleepstore merino is definitely a cut above the rest.
Best PJs ever
By Rochelle from Auckland on 6 August 2019
We have used these PJs for the past three years, they are simply amazing. They wash beautifully so can be handed down to your next child. I can't get my four year old out of his! Thank goodness they come in big kid sizes.
So Cosy and soft
By Jennifer from Wellington on 23 May 2019
I was so excited to order one of these and was not disappointed when it arrived. So thick and so cosy, it’s just beautiful. The merino inside really is like fleece, so soft and not scratchy at all. I also love that the neckline comes higher at the back so you know bubs will be nice and toasty during the coldest winter months. The sizing I found to also be generous, with my 6-12 m who’s on the bigger end.
Toasty
By Shannon from Te Puke on 8 May 2019
Mr 6 loves this suit ! I love how warm they are and wish they came in my size too! The fabric washes well and dries quickly also .
The Best Merino Sleepsuit
By Terryn from Auckland on 8 May 2019
Highly recommended these suits!! They are everything the description says and more!! I wish I found these sooner. My daughter has been so toasty and warm in this suit. It has significantly improved her (and ours) sleeping.
Beloved sleepsuit
By Nikki from Crowmell on 8 May 2019
This has got to be the snuggliest onsie you could ever own (if you are a kid). My 5 yr old has literally worn his to death. I have just purchased a second one as his first no longer has any knees...or thighs or shins actually. I tried to take it away with the intention of darning (or some such stuff) and didn't. Put it back in his drawer and the excitement on his face when he found it again was incredible. He would wear it all day, everyday if I let him. We well and truly voided all warranties there. He even wears it in summer...hot 30+ summers!
Great product!!
By Helen from Ipswich on 8 May 2019
Fantastic quality merino fleece. It's so soft and not itchy at all. Wish it came in adult sizes too!!

Sizing Guides
Here you'll find sizing information and measurements for our most popular styles. We make our styles true to standard sizing, often with a little extra for room to grow and the measurements below are approximate.
If you are buying for your little one to wear immediately make sure you get the size that's right for now and be on the safe side. This is particularly true when choosing between a 3-24month and 2-4year sleeping bag. If your little one is under 12kg and not yet comfortably fitting size 2 clothing, don't be tempted to go for the 2-4yr size thinking they'll grow in to it. Get the 3-24month size so that it fits them properly.
