Dear Mr. Marmot Person:
I have read several reviews about sleeping bags, and sleeping bag fills, by people who know what they are talking about. Andy Kirkpatrick says that 900 fill down is a myth, and that testing results differ from lab to lab. And it is well know that fill ratings are only accurate to a few percent.
But fill powers aren't my beef. While I don't believe the vast majority of manufacturer claims, as most are false, I don't like the fact the manufacturers can't give decent weights for their producst. While it sounds like a shameless plug, Golite is the only one who gives reasonably accuarate weights.
Get all huffy now. I don't buy Marmot for a variety of reasons.
