Great sleepsack
I love this sleepsack, so thick and warm perfect for the winter! Zipper works great and the pattern is cute its also so soft! I like that the leg zips all the way down for diaper changes makes everything so easy. Overall highly recommend

Cozy, good quality
My toddler wears this to sleep almost every night. It’s good quality and cozy. I like how it’s sleeveless because sometimes she gets too hot with the long sleeve sleepers. Has gone through many washes and is still in great shape.

Great for walkers
I love this footed sleep sack! My son disliked his normal sleep sack when he started pulling up and taking steps. We replaced the sleep sack with a blanket but he would kick it off and wake up cold in the middle of the night. Now he is snuggly and warm all night long and bonus, he looks absolutely hilarious, sort of like an adorable roast chicken. 10 out of 10.

Amazing quality!
Absolutely love this sleepsack for my baby! The quality is great, it is really soft jersey type cotton inside and outside. Two way zipper at the crotch - what a clever idea, definitely much better than snaps. I used to buy different brand that was a bit more expensive than this one, but their shop is closed and I am happy that I found this one, same quality but cheaper.

Zipper breaks easily
The double zipper at the bottom of the sleep sack broke within two uses. The sack otherwise seems of good construction, but a zipper is hard to replace once broken.

Perfect for winter months
This is perfect for colder homes in the winter . We have drafts and our bedrooms run a bit cold . This keeps my child warm and cozy . The quality is great . It washes well . The sizing is accurate . I have purchased a few now . The zippers work well too !

Big on my 9m old
Definitely can’t fit a 6m old in my opinion. My nine month baby swims in his
