PREMIUM FABRIC: Our incredibly soft blanket is made from 100% polyester microfiber yarn which is both strong and durable. Microfiber offers a sustainable advantage: garments made of microfiber last longer, reducing waste, and they require less water, energy, and heat during washing. Microfiber is thicker and not as heavy as cotton and will keep you warm in all seasons. This lightweight blanket has all of the warmth of wool without scratchiness.
