They all have 900 fill.
Of course, until they find that holy grail of synthetic insulation, goose down will always pack down smaller. That New River is a great synthetic quilt that will function better under wetter conditions and will be a little nicer on the wallet. It weights a little more and packs a little larger but hey, you cant have pros without cons.
