Huh?
A weak attempt at making down more impervious to moisture and therefore as effective as synthetic does not equate to synthetic becoming obsolete.
DWR is not a permanent treatment and will only hinder moisture saturation but will not stop it.
The ability of a synthetic fiber-fill bag, especially a continuous-filament fiber-fill bag, to work, regardless of the introduction of moisture, is unquestionable.
It's 'true down' that is becoming a thing of the past because duck feathers are being mingled with down as down becomes harder to source. The price of down bags will soon climb. A source in New York has 850-fill down listed at $75 / pound wholesale. That makes for a very expensive bag at retail or even at a pro-deal price.
Down don't grow on trees. It grows on geese. I love it the way non-hunters love to pick on hunters for gathering their own meat, then they climb into their "comfy down bag". Somewhere there are bare naked geese who are strong proponents of synthetic-fiber-fill bags!
Distance from the cold is the true insulator. Loft. By wearing too much clothing in an adequate bag, you are stifling heat from filling the loft. If heat does not fill the loft, cold air fills the loft and you will be cold because of the close proximity of the cold to your body. Wear as little as possible inside your bag. If you are cold, you are under-bagged or your bag is not efficient enough for conditions.
Interesting how some insulating mediums have to be re-invented and re-marketed every couple years to keep them relevant.
