Our Crescent Moon Bedding is expertly crafted using natural and organic cotton covers and 100% natural, organically grown alpaca wool blended with Sheep's wool. Alpaca wool is hollow, making it one of the warmest natural fibers available. It is also very light and soft so it is blended with sheep's wool to keep the wool apart and produce more loft. This bedding collection is naturally hypoallergenic. Alpaca wool's porous nature is naturally dry and clean which prevents dust mites and other allergens from settling in. Enjoy a comfortable, warm and healthy sleep with our Aplaca wool bedding.
