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. Review: 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. ## Features - “#1 Swaddle” New York Times: Rated America’s best baby swaddle, our SNOO Sleep Sack was designed by top pediatrician and world’s leading hip-safe swaddling expert, Dr. Harvey Karp.
