Hotel pillows and comforters are mostly feathers I believe. You also have to consider the hotel funk on pillow and especially comforter (BTW I never use the comforters in a hotel. They don't wash them a lot. Take a blacklight to your next hotel, turn out the lights, and shine it on the comforter. It will make you shudder.)
Speer Hammocks sells 900fp down. When I got my SnugFit under quilt from Ed Speer it had a certificate with it the certified the down in the quilt as 927fp (+/- 10% margin of error in fp rating it stated). First time I had seen a piece of gear actually include something that showed the certified rating on the down. I think it said 98% down and 2% feather and aother particles. I can dig the certificate out and post a pic if anyone wants to see it and if I can still find it.
