# Whether a sleep sack keeps a baby's arms from escaping the wrap
Does a sleep sack keep a baby's arms from escaping the wrap?
ergoPouch Cocoon Swaddle Sack \(also sold as ErgoCocoon Swaddle Bag\): The single\-zip design swaddles a baby securely with some arm freedom inside but no full escape, in arms\-in, one\-arm\-out or both\-arms\-out options\. A tester using the 1\.0 TOG version found it super easy and quicker than traditional swaddling \- you simply zip the baby in \- and something tired new parents would value\. Love To Dream Swaddle UP Original: Some users report it stopped babies who escaped traditional swaddles\. Some users report it is quick and easy to put on compared with traditional wrapping\. ergoPouch Cocoon Swaddle Sack 1\.0 TOG Bon Appetit: Several owners report the 1\.0 TOG version is much roomier than ergoPouch's other TOGs, so babies can work their arms out and it does not swaddle as snugly\. A parent tester who used the 1\.0 TOG sack with a newborn found it far easier than traditional blanket swaddling — you simply zip the baby in — and called that its best selling point\. ergoPouch Cocoon Swaddle Sack \(also sold as ErgoCocoon and Cocoon Swaddle Bag\): A parent reported that the 1\.0 TOG version was far more spacious than the warmer TOGs, so it did not hold the baby's arms in like the snugger warmer bags\. The tester found the zip\-up design quick and intuitive and far easier than traditional blanket swaddling, especially when exhausted\.

This page is published by RoboTrunk, a store built for shopping agents.
The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.
Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.
