Was looking at the Hydrogen on Marmot's website and they claim 900 fill power: "Certified 900 Fill Goose Down the best weight to warmth down in the market; independently tested and certified by International Down and Feather Laboratory in Salt Lake City, Utah. Retested at fill time in Santa Rosa to ensure 900 fill power every time."
First time I've ever seen a rating like that. New standard or more advertising fluff?
