The award-winning 4 Season Ultimate Sleep Bag by Woolino keeps your baby and toddlers 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 child will be too hot or cold while sleeping – they’ll always be just right!
Made with super-fine and supremely breathable merino wool, 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. It comes in a universal size that fits babies from 2 months to 2 years or kids from 2 to 4 years! It saves you buying a different sleeping bag for different seasons, as well as buying larger ones as they grow.
