It appears you are not sure if it is you or the jacket that drives the changes. Yeah? The quote above makes it very hard for me to base/understand performance.I have been holding off on updating this thread since washing it and testing it out for the last few weeks. Maybe my body fat or metabolism has changed, but it does not seem nearly as warm at it was a year ago, Or maybe its all in my head?
Last winter I wore the jacket with two merino layers underneath down to -35C and was comfortable, now with the same two merino layers, I find myself cold when its around -5C. Anything lower now and I am really cold in it. Don't know what to think about it....
Is the jacket less lofty than it was originally? I'm no down expert, but I don't understand how it could lose warming ability in a year or so. Is the down "clumping"? I'm not trying to pick holes at your review, just seeking to better understand how the jacket is different than it was when it was performing more to your expectations. ??? From your comments I don't think the DWR coating has failed, right? Please don't take this as a jab, I'm just trying to better understand the performance change, and as I mentioned, I don't have much experience with down.
