Shop King Size Alpaca Duvets and Bedding Sets from South House Alpacas. Our King Size Alpaca Duvets and Bedding Sets are super-comfy and luxuriously natural. Made from 100% alpaca fleece and natural cotton covers. South House Alpaca Bedding Sets are suitable all year round, as alpaca fleece works with your body temperature to keep you warm in the winter and cool in the summer – the perfect solution for a comfortable night’s sleep. All our alpaca duvets and pillows are Vegetarian Society approved; shearing the alpacas once a year is a harmless annual process to retrieve the beautifully soft fleece.
