Our Jersey Sleep Sack is a baby and toddler sleep sack designed for arms-out sleepers (usually from around 3 months of age). The Jersey Sack has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleep sack' after the swaddling phase is over. The safe-sleep approved design is made from soft, stretchy GOTS certified organic cotton and bamboo viscose that is non-toxic and gentle of baby's skin. The ergonomically designed sack features a bell-shaped bottom to promote healthy hip joint development and is approved by the International Hip Dysplasia Institute, and the material is stretchy to allow baby to move more freely and stay comfortable while they sleep. The 1.0 TOG Jersey Sleep Sack is perfect for keeping a child warm overnight in rooms 70-75F. The TOG rating means that there is no need for additional blankets in the cot when using this product, making it a safe-sleep option. Parents can be rest assured that the breathable organic and natural fibres will help regulate their child's temperature and prevent overheating. Parents can follow the FREE room thermometer and What to Wear guide provided with the product, to layer appropriately underneath to keep their child warm. We recommend pairing this pouch with one of our TOG-rated Rompers and Arm Warmers can be added on top of the pouch for extra warmth (all sold separately). The Jersey Sleep Sack meets all safety standards in Australia and New Zealand and is reviewed by the Eczema Association of Australasia as a skin-friendly product.

Please use your child's weight to find the most appropriate and safe size for them. A sleeping bag should be well fitted around the neck and the armholes to avoid your baby slipping through.
