The Happiest Baby SNOO Sleep Sack is excellent quality. The 100% organic cotton is soft, breathable, and gentle on baby’s skin. The design makes swaddling easy and secure, helping baby feel calm and comfortable. It’s well made, washes well, and holds up beautifully over time. A great investment for better sleep and peace of mind.

Can’t live without!! The ONLY swaddle our baby can’t escape! Extremely easy to use. Color exactly as pictured. Has lasted for several months, does start to lose velcro stick after about a month or 2 but the zipper keeps it secured. Not super warm, perfect for 70° sleeping temps!

I really liked the material of this product. It's thick and well-made. The tie-dye pattern is a fun break from the gray and white monotony of other Snoo products. Easy to use. MUST BE USED WITH SNOO SMART SLEEPER. If you are looking for a swaddle, pick the Happiest Baby Sleepea Swaddle.

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.

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.

I am so happy with the Baby SNOO Sleep Sack! From the very first use, it made a huge difference in how quickly our baby falls asleep—almost instantly after being swaddled. I’ve used it ever since my daughter was brought home from the hospital. The quality is outstanding. The 100% organic cotton is soft, breathable, and feels so gentle against baby’s skin. I really appreciate how well it’s made—it gives me peace of mind knowing our little one is safe and comfortable through the night. Love the strawberry design it’s just the cutest thing ever!

Works fine. Fits the snoo, but had a bad “packaging” smell when it arrived. Had to wash it twice.
