Our Cocoon Swaddle Sacks 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 swaddle can be used on its own in room temperatures between 70-75F with no blankets in the bassinet or crib to make this a safe sleep option for a newborn or baby and an ideal warm-weather swaddle. Parents can layer up underneath as needed for more warmth, and follow our handy FREE what to wear guide included with the product to help them dress their child appropriately. We recommend pairing this with one of our TOG-rated rompers underneath (sold separately). The Cocoon Swaddle Sack is made from natural fibers GOTS certified organic cotton and bamboo with a touch of elastane. This means it's firm enough to restrict startle reflex while 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. The soft, breathable organic cotton and bamboo is certified non-toxic, dyed with water based dyes, and gentle on newborn skin, and skin prone to eczema breakouts. 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 sleep sack when baby is showing signs of rolling. The bell shaped design is approved by the International Hip Dysplasia Institute as being hip-healthy, and promotes proper joint development in the hips and shoulders joints. Finally, the two-way zipper makes for quick and easy diaper changes during sleep with minimal disruptions. The Cocoon Swaddle Sack complies with AU, US, UK and EU safety and quality standards and is reviewed by the Eczema Association of Australasia as a skin-friendly product.
