    First time
  

*by J***K on Reviewed in the United States on March 4, 2019*

First time purchasing a duvet online and I was quite nervous as the prices were just too cheap compared to retail stores in the shopping center. Lucky I bought it, it was exactly what I expected to be. Great smooth cotton with no smells or odors that usually come from cheaply made comforters, but this had none at all! I love it. I’ll be purchasing this for the guest room as well !

### ⭐⭐⭐⭐⭐ 







  
  
    Light weight down blanket/comforter: The only blanket you need all-season.
  

*by J***S on Reviewed in the United States on March 3, 2019*

After unboxing I knew that this blanket was of good quality and would be durable.Here's what makes this a great product:1. Warmth is trapped and is a great insulator that will not overheat you. Feels like North Face thermo-ball jacket!2. You do not get tired in this blanket as it is very free-flowing. You can also wrap your legs around it because of its large accommodating dimensions.3. Say goodbye to a space heater. Save electricity because I am always wrapped up in this all-season.
