Size Guide
Cocoon Swaddle Bag
Please use your child's weight and height to find the most appropriate and safe size for them. To comply with safety requirements, our Cocoon Swaddle Bags 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.

- Abigail C.Verified Buyer7 hours agoReviewingCocoon Swaddle Bag 2.5 TOG Night SkyRated 5 out of 5 starsPerfect for winter/Autumn
As a first time mum I have absolutely LOVED these sleep sacks. They make layering for bedtime so easy especially with the TOG guide that comes with every purchase. Love layering this one with a 1.0 layer for a colder night.

We love this swaddle bag, we find sizing up is the best fit though!
- Kate M.Verified Buyer5 days agoReviewingCocoon Swaddle Bag 3.5 TOG DaisiesRated 4 out of 5 starsGreat design
So far it is good. I also purchased a 2.5tog. Both for winter. I prefer these over other brands due to the thicker material being on front and back. Others I have used are only at the front.
