Made of GOTS certified organic cotton that is both eco-conscious and gentle on baby's skin, every blanket is pre-washed, breathable, extra versatile, and ultra soft, becoming even softer with each use and washing. Black and white are more than just design choices.®  Why black and white? Research shows that high-contrast, black and white patterns enhance baby's vision and stimulate brain development. Why muslin? Muslin is known as a safer alternative to other fabrics to protect your baby from overheating.. The material is lightweight, breathes well and helps to regulate your baby's body temperature. Uses include: lightweight blanket, floortime play rug, stroller cover, nursing shield, change mat, giant burp cloth that (almost) never ends and much more! At a generous 47x47in, our blankets are the perfect size to grow with baby for many years! Our blankets can also be hung on the wall as a tapestry, used as a scarf, or worn as a sarong when your kids are big! Details: XL 47x47in. GOTS certified organic cotton muslin. Certified according to OEKO-TEX® Standard 100 to ensure the exclusion of harmful ingredients. Machine washable.
