Light weight knit grey Amma nursing cover. This was the only one my child would let me use to nurse in public. Worked great while pumping at work too! Has multiple ways to wear and use as car seat cover. Smoke free home. Yarn does have natural variations to grey color. Fabric Content: When selecting yarns we wanted one that was breathable and lightweight, easy to care for, and durable enough to last you a lifetime. We found the perfect Cocoon yarn in a blend that is 65% polyester and 35% regenerative rayon. Oh, and it’s wrinkle and stain resistant - doesn’t get any better than that!
