Our Cocoon Swaddle Bags are designed to be both easy to use and difficult to escape from. This zip-up swaddle is TOG rated for warmth to keep a baby snug and securely swaddled without the need for complicated wrapping from day one. Being TOG-rated means that the 1.0 TOG can be used on its own in room temperatures between 21-24°C with no blankets in the bassinet or cot to make this a safe sleep option for a newborn or baby. The stretch material allows for full chest expansion when breathing, added comfort, and for a baby to move its hands into a self-settling position inside the swaddle. A zip enclosure also protects your child's delicate skin, and the handy arm poppers transition the Cocoon from an arms-in swaddle to arms-out sleeping bag when baby is showing signs of rolling.
