Travel Size Alpaca Filled Pillow. We use 100% US Alpaca and US Organic Cotton because of its properties. Alpaca fiber has a semi-hollow core, deterring dust mites, which are the leading causes of asthma and allergies in the bedroom. This porous fiber creates an extra insulation value for a constant balance of temperature when we are in contact with it. Alpaca is naturally fire resistant! No toxic chemicals needed!
