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 warm and safe without the need for complicated wrapping from day one. Being TOG rated means the 1.0 TOG swaddle can be used on its own at room temperatures between 70 and 75°F without blankets in the crib, making it a safe sleep option for a newborn or baby and ideal for warmth. The Cocoon Swaddle Sack is made from natural GOTS-certified organic cotton and bamboo fibers with a touch of elastane. This means it's firm enough to limit the startle reflex while still allowing stretch and movement for healthy growth. The stretch also allows for full chest expansion when breathing, increased comfort, and allows baby to move their hands into a self-settled position inside the swaddle. The soft, breathable organic cotton and bamboo are certified non-toxic, dyed with water-based dyes, and are gentle on newborn and eczema-prone skin. A zipper closure also protects your child's delicate skin, and convenient arm snaps convert the Cocoon from an arms-in swaddle to an arms-out sleep sack when baby shows signs of rolling over. The bell-shaped design is approved by the International Hip Dysplasia Institute as hip-healthy and promotes healthy hip and shoulder joint development. Finally, the two-way zipper allows for quick and easy diaper changes during sleep with minimal disruption. The Cocoon Swaddle Sack meets AU, US, UK, and EU safety and quality standards and is reviewed by the Eczema Association of Australasia as a skin-friendly product. Features:
