1. Alpaca wool, down and feathers all keep you warm, which is what they have in common, and this is fantastic when you first drift off to sleep. All snuggly and comfortable, all night long. Except that with down and feathers, you don’t get the level of temperature regulation you would get with alpaca wool. Alpaca wool insulates you from the cold but lets enough air in to keep you cool and comfortable, for a better night of sleep. Alpacas live at high altitudes and they endure the coldest winters and the hottest summers imaginable. Their fur is perfectly evolved to resist this and this makes it perfect for you.
2. Down keeps you warm but you might get, and stay, a little too warm because it cannot regulate temperature like alpaca wool can.
3. Alpaca wool is resistant to dust mites, whereas down and feathers attract dust and dirt.
4. Down is comprised of small feathers and often mixed with larger feathers in pillows and duvets; however, it doesn't stay even and you’ll eventually find holes and gaps in your duvet, where the feathers have settled unevenly.
5. Lastly, down and feathers are likely to come from factory farmed birds while no such thing exists with regards to alpacas. Also, alpacas are never kept for their meet.
