Love the idea and design of these sleepsacks but it just did not work for my 10 week old baby. The quality is the best out of all the sleepsacks even Halos. I would recommend for other parents to at least try it for a week or so to see if it helps their babies sleep better. Just make sure to keep your receipt and box if it's doesn't work.

I’m a new mom and I completely understand that not everything works for everyone’s child. But reading the reviews I got super excited this would work ! My almost 3 mo old does sleep about 6/7 hours straight through the night but only when co sleeping with me . When he’s sleeping in his bassinet he’s up every 2/3 hours I was very excited to try the zen sack in hopes of getting my bed back lol . But unfortunately it does not work for my son !

No difference from any other sleep sack/wearable blanket. Not with the cost.

We were looking for something to help our little one sleep and this was not at all what I was expecting. I returned it so I could try something else.

My little one always has to fall asleep with my hand on his chest, this sleep sac has helped him fall asleep a lot faster without my hand!

Great sleeper for my baby boy. It definitely helps with putting him to sleep. Its also great to use once he starts turning over and we couldn't swaddle him.

Good for baby sleeps good

Our four month old loves this sleep sack. When we transitioned out of the swaddle, we tried a couple different options and she slept best in this one.
