Michael, the stuff I saw at OR this past summer (from numerous manufacturers) retained loft by ~30%.
I humbly suggest doing a bit of homework on the technology, as many do on this forum, before making some of the generalizations that you have made on this thread.
I've been corrected by far too many to count on this forum and appreciate every bit of it, as it helps educate me on the obscurities of outerwear, gear, backpacking light, etc.
We are all looking for accurate information to HELP best inform us on our gear decisions, let's keep it that way. :)
