Extra cozy and featured in our signature, hand-painted prints, our Quilted Sleep Bags are a safe and warm blanket alternative during the cooler months of the year. Quilted layers of soft cotton muslin keep heat inside while a unique, breathable design allows air to flow freely ? creating a comfortable and cozy sleep environment for baby throughout the night. Included are parent-loving features like a two-way zipper for easy nighttime diaper changes, and machine washable cotton muslin that gets softer with every wash.
