The award-winning 4 Season Ultimate Baby Sleep Bag keeps your baby at a perfect temperature throughout the night, year-round. That means there’s no need to worry about which weight sleeping sack to use, or whether your baby will be too hot or cold while sleeping – they’ll always be just right!
Made with super-fine and supremely breathable merino wool and organic cotton, it helps keep your baby warm when it’s cold and cool when it’s warm. That temperature regulation means that your baby will sleep comfortably throughout the night– and that means a better night’s sleep for you too. Cuddly-soft organic cotton outer adds to the comfort as it's perfect for the most delicate skin.
