  • Great Sleep Sack!
Color: White Size: Small
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
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!

  • Best swaddle/sleep sack!
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- newer design
Love the piece that goes between the legs to keep baby from sliding down like the older design.

  • Strawberry Snoo Swaddle
Color: Ivory Strawberries Size: Small
I love that the color of the swaddle is cream and matches the bedding that comes with the Snoo perfectly. I do wish the swaddle was able to be dried in the dryer at high heat. When I take the swaddle out the inside parts that Velcro are still damp and it takes some time to be fully dried. When it comes to having babes, you always need more than one or two swaddles because of blowouts and spit ups. ... show more
