This is such an amazing article. I loved reading this.
We purchased a Hutterite 850 loft-500 duvet(all season) . I was worried realizing it was so light.
We purposely sleep in a cool room temperature.
It was fantastic. The bedroom was at 15c or 59F. The duvet kept us warm the entire night.
We don’t even wear Chanel no 5 to sleep.
