5 week old baby sleeps happily in his Snoo sacks!
I purchased the Snoo Sleep Sack in the Teal Planets color in size small and I have been very happy with it for my 5 week old. The fabric on this version feels noticeably softer and stretchier than the plain white Snoo sacks that I also own. My baby is over 9 pounds and 22 inches long and the Small is still fitting him well while allowing him to sleep comfortably. It's so easy to swaddle him with the velcro and zip up closure. It does a great job regulating temperature. Even during winter we do not need to layer him heavily and he sleeps very well in this sleep sack. He always seems comfortable wearing it and despite being only 5 weeks he is starting to have long sleep stretches! I definitely think part of this is because of how cozy he feels in his Snoo sacks! I would definitely purchase more of these and would choose this fabric over the plain white versions due to how soft and flexible it feels.

Well made, good color to see leaks
You can’t use the snoo without them so I give it 5 stars. I do like the double zipper, the mesh to air out the swaddle and the material is think and durable. The gray is a great color bc then you can see if the swaddle is wet from a diaper leak or a spit up.

Easy, Secure, Cute, and Baby Approved !
This swaddle is way better than the standard white one that came with our Snoo. The material feels softer and sturdier, and my baby clearly prefers it — he settles faster and sleeps more soundly in this one. The zipper is smooth, it’s easy to wash, and it holds up great. Definitely worth getting as a backup or upgrade to the original. Sizing runs true, so if your baby is on the longer side, you might want to move up to the next size sooner than expected. Overall, this swaddle is a total win in our house. It keeps our baby safe, soothed, and snuggled — and that means a lot more sleep for us too.

The softest Snoo sack yet and the Tie Dye is adorable!
We own a few different Snoo sacks, but this Tie Dye Rainbow version is by far my favorite. The 100% organic cotton feels noticeably softer and higher quality than the standard white ones. Why we love it: • Design: The tie-dye print is super cute in person vibrant but still gentle enough for a nursery. • Softness: It washed really well and stayed incredibly soft against my baby's skin. • Function: It works exactly like the original sacks (clips in easily), but adds a nice pop of color to the bassinet. Verdict: If you want to mix up the plain white look, this is a winner. Highly recommend for the softness alone!

Made nighttime routines easier for a new parent
This was a great purchase, especially for my husband who was not very confident with traditional swaddling. Getting a baby wrapped securely can be challenging, especially during those late-night feedings when everyone is tired, and this sleep sack made the process much easier. I really liked that it helped our baby feel secure and comfortably wrapped without having to struggle with getting a perfect swaddle every time. It was simple to use, which made those middle-of-the-night changes and feedings much less stressful. The material also felt breathable and comfortable. I felt better knowing our baby was cozy without feeling overly warm. The design made it easy to put on and take off while still keeping the snug feeling babies often like when sleeping. Overall, this was a great addition to our baby essentials. It is especially helpful for parents who may not feel confident with traditional swaddling or just want something quick, easy, and reliable for bedtime.

Overall nice but not the same quality
I bought this as a back up for the swaddle that came with our Snoo rental. The positives are that it’s held up with multiple washes without shrinking and I really like the two way zipper (so I can sneak the owlet sock on). The downside is that I noticed the Velcro part has pilling on it which didn’t happen with the swaddle I got from the company. I did get this swaddle on sale on Amazon and have seen it happen occasionally where it’s around $25 so I would definitely wait for that.

Amazing swaddle
I've been using the snoo for about 4 months now. We had received some old swaddles where there wasn't enough room around the hips to allow for my babies legs to be in frog position while he slept, so i decided to purchase the newer version and they're amazing. There is so much room for him to be comfortable. The velcro is sturdy and snug. The sizing is accurate. The buttons around the shoulders allow you to use it as a sleep sack once your baby isn't being swaddled anymore. Cleaning is a breeze, very easy to get stains out of it even though it's light in color. The only disappointing thing was that the color was more beige/yellowish than white. We also had to wash it a couple of time once we received it as it was hard to get that factory smell out of it.

Muy buena compra!
!La verdad me gusto mucho este producto! Va creciendo junto a tu bebé, aunque considero que debería de haber tamaños más grandes, mi bebé solo lo pudo usar 1 mes (de 4-5 meses), compre el grande, y aunque no pesa ni los 8 kilos de lo largo le dejo de quedar.

Genuine sleep sack, my baby loves it with the Snoo
Nice and soft sleep sack which fits my 2 month old (big baby). It’s a snug fit but thanks for it being stretchy it isn’t restrictive (any more than it should be). Washes and tumble dries well - just make sure to fasten the inner bands together beforehand otherwise the Velcro sticks to everything! A nice range of colours from the manufacture, although I find this design is one of the most available ones to buy.
