I found that review interesting, I can understand the guy wore the down piece during the day to test it out but in those conditions I would always pick fleece first time and synthetic as a far second.
You may remember I wrote about the Brooks Range Mojave but did not get to test the DWR Down as the jacket was not warm enough for spring conditions an thus snet it back for a refund.
Even with DWR Down I feel syntehics will still have a time and a place, on Eric Chans advice I have been using a Sntehic Parka over a down inner, I have also purchased a syntehtic quit to use as and overbag. Besides the obvious advantages of the quilt I realised I could tuck the quilt in to the hood of my sleeping bag meaning I only breathed on the quilt. The quilt is a 50F and weigh 395g and can replace a bivy when used using a single skin shelter.
