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.

- AlanaVerified Buyer5/29/25ReviewingCocoon Swaddle Sack 3.5 TOG DragonfliesRated 2 out of 5 stars3.5tog starts 1/3 way down
We bought the ore expensive warmest tog (3.5) for our 3 month old heading into winter, however the warmest/thickest part doesn't actually start until 1/3 the way down where his body is, and so his top half is still cold overnight with just the thinner layer. Disappointed as we have loved ergopouch over the years for all our babies.
