It's probably a topic as old as down jackets have been around. I was surprised when looking at an Eddie Bauer down jacket recently to see the feather content listed at 20% (not a First Ascent model). Is this a statistic to inquire on any down jacket purchase or are reputable outdoor brands keeping the feather percentage low or at zero. The negative of feathers I assume is they don't have any desirable characterics like down, compressibility, loft, non-allergenic, etc. In summary, 20% seems unacceptable to me and I did not buy the jacket.
