The award-winning 4 Season® Ultimate Toddler Sleep Bag keeps your toddler 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 toddler warm when it’s cold and cool when it’s warm. That temperature regulation means that your child 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. It comes in a universal size that fits kids from 2 months to 2 years. It saves you buying a different sleeping bag for different seasons, as well as buying larger ones as they grow. You just need one Woolino sleep bag for your toddler that will fit for 2 years. Good used condition; washed with scent free detergent and always hung to dry. Comes from a smoke free, pet free home.
