I have the summer weight comforter, which is perfect for me as I run cold but live in an overheated apartment. It's very lightweight and very warm. I love that the fabric used is tightly woven and keeps out dust mites, which means I don't need an additional allergy barrier cover. My previous duvet was made of sheep's wool and had an allergy barrier cover on top--it was much heavier and squashed my feet. The one thing that would make this alpaca duvet even better would be corner loops/ties so I could secure my duvet cover to it, as the duvet shifts around in the cover without them (I decided to buy comforter clips to fix this problem, but they are a little bulky).
