This down alternative comforter is amazing.  It's incredibly warm, a great weight, and soft.  I've only had it for 48 hours and I can't imagine ever sleeping with anything else.  It came vacuum sealed, and said give it 48 hours to puff up, which it has, and it's amazing.  I'd buy this time and again, and recommend it to anyone.  

Pros: Warm; nice weight to it
