Aha. So the Uniqlo parka IS a lot puffier than the UL jacket. Based on these ranges, perhaps 50% to 85% puffier. (My UL Jacket measures 7/8," double layer.) Looks like the parka is more than just a different cut and an added hood. It's built for colder weather.
>Stupid question but is the ruler you put on top of the down compressing it any?
It's a lightweight plastic ruler, and it floats on top...there's no "indentation" in the down caused by it, so I'd have to say, no. I use the plastic horizontal ruler to pick up an average of the loft across multiple baffles...so I'm not measuring at just one point. I take several measurements and average the results.
In case you're wondering: yes, I gave the jacket a good shake before measuring, to get it as lofty as I could.
Back to the parka:
A CLO calculation would put the parka around .75 (single layer) x 6.5 (Nisley's 800 down multiplier) x .52 (parka) = 2.5, give or take. For comparison, my UL jacket calculates out to a CLO of 1.4.
