  • 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. BEST. SWADDLE.
Color: Midnight Planets Size: Small
The best swaddle ever. Easiest to use, holds up well with washing, helped baby sleep longer. AMAZING

  • 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

  • AMAZING
Color: Ivory Planets Black Wings Size: Large
if you have the snoo this is a MUST HAVE. The Velcro holds up so well with frequent washes, we have the Snoo ones as well and he’s able to slide out and the velcro slipped up around his neck - I caught it within seconds because I had that eerie feeling with the poor quality velcro so I was watching him sleep lol But this tightens around the torso so if you need to transition their arms out of the velcro, it’ll still keep them from wiggling free in their sleep - has to be pretty deliberate if they want those things free The leg is extra roomy for all his kicks and movements. 10/10 love these ... show more
