Customers overwhelmingly praise these sleeping bags for transforming infant sleep, highlighting the soft, luxurious fabric and innovative arms-in/arms-out design that reduces startle reflexes and helps babies sleep longer and more soundly. Reviewers consistently note exceptional durability, with bags retaining quality after 100+ washes, and appreciate the practical zipper design, TOG guidance, and shorter length for side-sleeping cots. The ease of use compared to traditional swaddling is frequently cited as a game-changer. A very small number mention zipper placement concerns or sizing issues, but these rarely deter repurchasing. Overall, most customers consider these essential for restful infant sleep.

Best sleep sack
Once transitioned our 8 week old started sleeping through the night
Just what we needed
Keeps my baby appropriately warm. She is done using the swaddle part and just uses it as a sleep sack now- no complaints!
Baby loves
Soft, beautiful Most importantly the baby sleeps comfortably
No complaints from bub or I
Love! Takes the hassle away from swaddling. The double zips make it easy access for nappy changes at night. Bub can freely move her arms but still be a snug fit so she doesn’t startle herself.
Perfect
Bought this for my new granddaughter. Born in May and the single tog warmth is just perfect for the summer weather.
Ten out of Ten
We use this every day for our bub, and it’s in excellent condition despite regular washing.
Great sleeping sac
Perfect for newborns, to swaddle or keep arms out. Stretchy and soft. Machine washable and also fine in the dryer.
Perfect for new borns
My little girl loves it. Much better sleep and she also looks super cute 😍
Favorite sleep sack
Amazing product. Got after 3 month old baby has been sleeping with his arms out of swaddles. Love the ability to snap the arms in or unsnap to have a vest sack. Excited to see how my next bat will like this one while they are still needing to be swaddled with arms in. Quality and comfort i amazing. Got on sale so I believe it was worth the price. I think my baby sleeps more soundly on his own in the sleep sack.i like to put him in a Long sleeve onsie underneath with arms out.
Love!!
This is my newborn’s favourite swaddle bag as loves his arms out when he sleeps. Easy to wash and dry and the quality is amazing!
Fantastic sleep sack
We have been using this sleep sack since our baby was about 3 weeks old. He loved to have his arms free of a swaddle, so this offered us the ability to calm and relax him while also letting his arms be free. I have already repurchased multiples of this in a bigger size, and plan to keep using this as our baby grows.
Must have!
We LOVE these sleep sacks so much. They are so soft & comfortable and wash well.
Sizing issue
I’ve written an email about my complaint over a week ago and no response back still
Best place for my baby to sleep!
So much easier to make sure my baby was wrapped up and safe every night
My favorite swaddle
