Hey guys,

I was just wondering if anyone had some data on the weight difference between 600-fill and 800-fill down.

Say, for example, that I filled 2 similar quilts with the same volume of each...would one be lighter than the other, or would it only be an issue of warmth?

Also, is down the best possible warmth-to-weight ratio, or are any of the synthetics like Primaloft or Climashield comparable?

Thanks in advance.
