Size Guide
Cocoon Swaddle Sack
Please use your child's weight to find the most appropriate and safe size for them. 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. You should be able to put 2 fingers inside the neck opening for the correct fit. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

I adore all our ergo pouch's and use the bags for over a year now with my oldest. I gave their new cocoon swaddle for my newborn a try and I love it! It's SO easy to put on compared to all the other sleep sacks out there, no extra steps which I love in the middle of the night. Just one easy zip up, and its like a sleep bag but tighter up top to swaddle that startle reflux. It's stretchy so baby can adjust and move but not too tight. I love the tog options and organic cotton. I wish they were a bit longer to accommodate them for longer as my baby is rapidly moving through sizes but overall, 5 stars!
