Overview
Description
The ergoPouch Cocoon Swaddle Sack works from the first night home through the rolling transition. Use it as a full swaddle with arms in, in a hands-up position, or unswaddled entirely — whatever works best for baby. When baby starts showing signs of rolling, unzip the wings and it converts to a sleep sack with arms out.
The two-way zipper keeps the swaddle secure through the night with no breakouts, and opens from the bottom for fast diaper changes without fully unwrapping baby. A bell-shaped bottom gives legs room for natural movement and healthy hip development.
Made with GOTS certified organic cotton and breathable natural fibers. Rated 1.0 TOG for a warm sleep environment, eliminating the need for loose blankets. Certified non-toxic and gentle on delicate skin. Machine wash and dryer friendly.
Sizing note: Unlike clothing, swaddles should fit snugly to help calm baby's startle reflex — do not size up. The Newborn size is recommended for almost all newborns, including babies who have lost weight after birth.

Just what we needed
Keeps my baby appropriately warm. She is done using the swaddle part and just uses it as a sleep sack now- no complaints!

No complaints from bub or I
Love! Takes the hassle away from swaddling. The double zips make it easy access for nappy changes at night. Bub can freely move her arms but still be a snug fit so she doesn’t startle herself.

Favorite sleep sack
Amazing product. Got after 3 month old baby has been sleeping with his arms out of swaddles. Love the ability to snap the arms in or unsnap to have a vest sack. Excited to see how my next bat will like this one while they are still needing to be swaddled with arms in. Quality and comfort i amazing. Got on sale so I believe it was worth the price. I think my baby sleeps more soundly on his own in the sleep sack.i like to put him in a Long sleeve onsie underneath with arms out.

This is my newborn’s favourite swaddle bag as loves his arms out when he sleeps. Easy to wash and dry and the quality is amazing!

Fantastic sleep sack
We have been using this sleep sack since our baby was about 3 weeks old. He loved to have his arms free of a swaddle, so this offered us the ability to calm and relax him while also letting his arms be free. I have already repurchased multiples of this in a bigger size, and plan to keep using this as our baby grows.

Worth the money
A lot of the bad reviews seem to be due to people having the wrong size. This has by far been the swaddle my baby loves the most. It’s snug enough to comfort but still allows for some movement. The swaddle feels well put together and like it will last. By far our favorite swaddle and worth the money. Love that it transitions to arms out to make it last longer
