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 2.5 TOG can be used on its own in room temperatures between 17-23°C / 63-73°F with no blankets in the bassinet or cot to make this a safe sleep option for a newborn or baby. The chest area is 1.0TOG rated to prevent overheating and allow for full chest expansion when breathing. The Cocoon Swaddle bag is made from natural fibres GOTS certified organic cotton and bamboo with a touch of elastane. This means it's firm enough to restrict startle reflex whilst still allowing stretch and movement for healthy growth. The stretch also 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.
