  • Great Sleep Sack!

Adorable sleep sack for your little one! Purchased this for a baby shower bc it was on her list. Its adorable! Great quality.

  • Fits like a hug
Color: Teal Planets Size: Small
Great product. Personally like this fabric compared to the canvas like material baby sack the snoo comes in. The fabric is much softer and the wife loves the color as well. Fits perfect with the basinet, and stretches perfectly to the baby. No smell of any chemicals, not too heavy or thick for the season. Very easy to use especially due to the light fabric material. ... show more

  • The only way my baby would sleep.
Color: Graphite Stars Size: Medium
Loved this swaddle. My sons would ONLY sleep in a swaddle and this was by far the best one we purchased. Kept his little arms down and thus made for a great night sleep for everyone. Him and us!

  • Even better than the old model!
Color: Ivory Planets Black Wings Size: Medium
At first I disliked these and favored the older ones that didn’t have the in between the leg Velcro but I’ve come around on them! I like that they encourage the legs to frog out for proper hip development - it also seems to help tall babies stay in the snoo longer. Two small cons: I like to put a heating pad in the snoo to preheat it before bedtime. The Velcro on the tail piece is sticking up so it always attaches to the heating pad. Not a huge deal but hard to detach one handed when i’m juggling a sleeping baby. The second con is I have found that these take a while to dry in the dryer. I usually have to put them in for 30-45 mins extra. The back band that secures the sack to the snoo is the culprit here. Pros definitely outweigh the cons tho! Great product. ... show more

  • Best swaddle/sleep sack!
Color: Teal Planets Size: Medium
We tried many different brands including the Halo and this one is the best. It’s snug enough, good quality material, and my son sleeps so well with it. He has slept 8-9 hours every night since 6 weeks old.

  • Great arms free option
Color: Graphite Stars Size: Medium
This is just like their other snoo sacks, material is exactly the same. It’s great since my little one now likes to sleep with her arms up and uses her hands to self soothe. However the snaps are hard to snap and unsnap and the location seems like they would hurt her arms when her arms are out and the snoo is rocking back and forth. ... show more

  • Great- newer design
Color: Rose Planets Size: Medium
Love the piece that goes between the legs to keep baby from sliding down like the older design.
