So good, I ordered another one!
The Transitional Swaddle Sack has been a game changer for our baby’s sleep routine. The material has the perfect amount of stretchiness, giving our little one enough movement while still providing that snug, comforting feel. Since using it, our infant has been sleeping almost through the entire night, and the improvement in sleep quality has been amazing. The zipper quality is excellent,smooth, durable, and makes nighttime diaper changes quick and hassle-free. It’s incredibly easy to use, even when you’re half-asleep during late-night changes. The fabric is breathable, keeping our baby comfortable without overheating, and soft enough to feel gentle on their skin. Overall, this swaddle sack offers the perfect mix of comfort, flexibility, and convenience. Highly recommended for any parent looking to transition their baby safely and comfortably!

It actually worked
I’m not one to write reviews, never have actually so this is my first one but after a couples months of use I just had to leave my thoughts for those on the fence. My baby was very heavily reliant on swaddling to be able to sleep and had a really aggressive startle reflex so when trying to take it away it was a total nightmare. I decided to give this one a try after failing over and over to get him to sleep without a swaddle. I’m so glad I did cause he loves this transitional swaddle! Been about 3 months of using it and I’ve gotten him back in his own sleep space and taking naps independently again and having longer stretches of sleep (on days/nights I don’t use it cause it’s dirty he doesn’t sleep as long and wakes himself up all night). It’s contoured enough to feel “snug” but still has plenty of leg room and can still put his arms down but helps lessen the arm flailing a lot. Love the double zipper feature and it’s very soft and just thick enough to keep him warm but not overheat. I highly recommend this product for the parents out there struggling to transition out of a traditional swaddle. I got the green one for reference, I read other reviews that said different colors seem to have different fabric and construction and the green one seemed to have the best construction so I went with that one and am definitely gonna get a few more now that I know my baby likes it. Hope this helps

Best sleep sack
Love these sleepers so much I went back for more. I love that we can free up a hand so my baby can self soothe. The material is thick and soft, easy to clean. The zippers are well made. I will say the ‘“mittens” to close off the arms do tend to stretch easy, so whether or not I leave my baby’s hand out, he always wakes up with both arms out anyways lol. I like the fit, it’s nice and snug, giving my baby comfort while he sleeps but also long enough to ensure there’s plenty of leg room. 10/10 will continue to use and buy

Great transitional sleep sack
Game changer! I needed to find something to replace the traditional swaddle since my 3 month old started rolling. I was so concerned it would interrupt his sleep because he started sleeping through the night. It took a couple nights for him to get used to this transitional swaddle but once he did he loves it and sleeps through the night again. At 4 months I tried to get him to sleep on his own for naps, it was a struggle at first but once he associated this sleep sack with sleep he would self soothe and fall asleep in this. The arms for a perfect tension for the startle reflex. He’s 5 months now and doesn’t really have startle reflex but he loves his sleep sack so I’ll keep him in it for a while. Also he runs really hot so the 0.5 Tog is perfect

Odd sizing, but great product
I originally got the size small for my two month old, and I was gifted a couple of the exact same brand/style/size and they were bigger than the two I received. the different designs have different sizes it seems but these are otherwise great. They keep my baby warm at night and keep her from startling when I wake her up to feed her. It's very soft and a little stretchy (but compressing enough to have a bit of a swaddle effect which I love), and they're so cute. I just wish the sizing was more standard so I knew what size she'd fit best into.

Perfect transition swaddle for arms up sleepers
Must have for a baby that loves sleeping with arms up. These were perfect for transitioning over to a sleep sack. Started with hands covered and then let her hands free at night. Once she was too big for a swaddle I moved her to a sleep sack seamlessly thanks to these. Great material, not too thick or thin. Has a slight stretch so cut can conform to baby and make them feel swaddled. Very easy to use because of the two way zippers as well.

I 100% recommend the SwaddleDesigns sleep sacks.
My little and I absolutely LOVE these SwaddleDesigns transitional sleep sacks... we have them in heathered denim, jadeite, turtle, yellow, turquoise, and cream colors. Baby sleeps really well (like from 8pm to 6am) every single night he has one on! With just one layer of the fabric, he can wear a onesie and socks underneath and be perfectly comfortable. These do NOT stretch, but they might give a little bit. They make nighttime diaper changes soooo much simpler with the double zipper and the sack shape... I cannot stand having to pull baby's leg out of a sleeper leg just to change him now - we're so spoiled these days... lol! Overall, we're very happy.

Super comfortable but zipper pulls consistently break off
I love the softness of the material and the foldable sleeves. My baby sleeps very well in these sleep sacks. Only giving three stars because the bottom zipper pull has broken off 3 of my sleep sacks in the laundry.

Adepte des produits similaires de grande marque, j’ai voulu tester moins cher, affectivement ça fait le boulot en revanche on voit que la qualité n’est pas forcément au rendez-vous, le tissus en coton est bien en revanche la fermeture de qualité moyenne est très épaisse, elle fait des gros bourrelet, et remonte dans le cou de mon bébé je ne suis pas fan de cette gigoteuse, elle est très rigide, j’imagine que c’est normal pour le prix mais sur les autres marques on a des fermetures plus souple donc pas gênante pour l’enfant. Si je dois en racheter une malheureusement je repartirais sur des grandes marques
