To comply with safety requirements, our Cocoon Swaddle Sacks have a firm fit around the neck, shoulder and chest area to prevent your little one from slipping inside.

I love this item. It’s nice I felt my baby is safer with it.
- Laura L.Verified Buyer2/18/26ReviewingCocoon Swaddle Sack 2.5 TOG SageRated 5 out of 5 starsLoves it!
My baby loves the warm cocoon that the ergopouch provides. We keep the house cold and she sleeps snuggly and warm in this.
- Taylor M.Verified Buyer2/18/26ReviewingCocoon Swaddle Sack 2.5 TOG DragonfliesRated 5 out of 5 starsGreat Quality and Customer Service
When we had an issue with incorrect sizing from manufacturing the customer service team was fast and efficient correcting the issue.
When we received the new swaddle in the correct size the quality is top shelf. My little guy sleeps so soundly in it. I love that it works for the swaddle ages and then can transition to arms out. I also love the TOG rating and the included card that shows room temp and how baby should be dressed. Having a winter baby in Alaska, I am always a little worried whether baby is warm enough and this gives me piece of mind so I don't hot box my little guy!
