Size Guide
Cocoon Swaddle Bag
Please use your child's weight 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.

- Alyssa H.Verified Buyer3/5/25ReviewingCocoon Swaddle Bag 3.5 TOG WillowRated 5 out of 5 starsPerfect for our first camping trip!
We took our little one on her first camping trip at 7 weeks. Needed a safe swaddle that would keep her warm in low 50s (F) temps. We put her in a short sleeve bodysuit, a long sleeve flannel onesie and this and she was perfectly toasty warm and not too hot all night long. Slept 7.5 hrs straight both nights! Couldn’t find many similar products to this, grateful something is made for the under 4month babies!
