Packed sizes for Econ 20 Incubator and Econ? Pictures?

Can anyone share what their normal packed dimensions are for the Incubator and Burrow Econ 20? Maybe post some pictures next to the Nalgene bottle or some standard size item?

I’m not that familiar with what to expect from lower-temp down quilts.

Right now I’m working with heavy (and big!) synthetics (Marmot Trestle 30 sleeping bag and... the Snugpak Under Blanket). I’m trying to estimate how much pack volume I’m going to save by going with down. I can figure out the weight savings, which is about half the weight...

For the Burrow Econ 20, HG provided stuff sack is 5.5 liters:

Compression / Pack Size
The Stuff Sack we ship with this quilt is approximately 5.5 liters in volume, but due to the nature of duck down, it can be compressed further with an aftermarket compression sack. We do not recommend keeping the quilt compressed for more than 24 hours, and should be stored in the provided cotton storage bag, when not in use.

So say 3 liters ballpark number if you really scrunch it down. Subjective by any measure so YMWLV, but suffice to say it's hugely less volume than equivalent rated synthetics.

Thanks for the comments, that was helpful.
