Gypsy Mama Bali Baby Breeze Wraps are made from a flat, bottomweight gauze. These wraps are wide and easy to spread, making them especially nice for back carrying, even with young infants. Gauze is a wonderful fabric choice for baby carriers -- cool in the summer, and no bulk over or under winter clothes. These wraps come standard with an end pocket, which is great for tucking the whole length of the wrap into for storing, and they are compact enough to toss in a diaper bag or purse. The dye is free of heavy metals and any other harmful substances and is safe for baby clothing.
