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.

- danya s.Verified Buyer6/13/25ReviewingCocoon Swaddle Bag 0.2 TOG Sweet OrchardRated 5 out of 5 starsCan’t live without ergopouch
This swaddle has been a total game-changer for our sleep routine. The 0.2 TOG is perfect for warmer nights — breathable, soft, and lightweight. I love how easy it is to zip up, especially during nighttime diaper changes. My baby feels secure but not overheated, and the fit is just snug enough to calm the startle reflex. We noticed longer stretches of sleep almost immediately! Can’t recommend it enough — we now have multiple on rotation.

With the warming weather, I was concerned about how to swaddle my little one. There truly aren't many options below 1.0 TOG and we were right on the edge temperature wise. My little one runs hot so we had to try this and I love it! It was a little looser than the 1.0 TOG swaddle, but it was still within safe sizing for my little one. The double zipper is great for middle of the night changes!
