Ok .. I KNOW that it is not a phd thread
But me and my climbing partner have several phd garments and sleeping bags
VERY GOOD products no doubts about
but about the "European 900 fill power" CLAIM … I have serious doubts about …..
In the last years I bought about (Im not sure)a minimum of 6 down jackets and more than 14 sleeping bags for me and (mainly) close friends coming for very good manufacturers as phd, nunatak, western mountaineering, yeti poland,marmot, diamir (spanish brand) and laila peak (spanish)
Honestly I can´t notice the difference with, as an example, other western mountaineering or Nunatak garments/sleeping bags that I own/owned
All of them are REALLY GOOD products (notice capital letters ;-)
As many brands does ( and did before) is a temptation claim that you have the "best down" because is the easiest way to be "the best"
Maybe for that reason the only way to make a difference is to claim "highest fill power"
real or not ……
