The 4 Season Big Kid Sleep Bag keeps your child at a perfect temperature throughout the night, year-round. Made with super-fine and supremely breathable merino wool, it helps keep your kid warm when it’s cold and cool when it’s warm. That temperature regulation means that your child will sleep comfortably throughout the night. It comes in a universal size that fits kids from 4 to 6 years. This has been worn a handful of times, in USED but great condition. It's for a young child (4-6yrs), hence the long length needing to be folded in the first photo! Night Sky print/color.
