Loftiest down Parka ever made?

I have an 8000m Marmot Parka. I have checked virtually every other parka I can see in store, and during my time in Alaska, and I have not seen a loftier parka. The feathered friends Rock and Ice was the closest I have seen. Does anyone own a parka that has more loft than this one?

My North Face Himalayan Parka is pretty ridiculous, but I haven't measured it. Super warm but probably the worst parka available if you want to do anything except slog up steep snow slopes - anything technical is out of the question.

I'm traveling but will try to measure it when I get back home this weekend.

Yea these 8000m parkas are not designed for technical climbing at all. Although this one isnt a bad fit. Let me know what you end up with.
