Don't overstuff them too much or you will defeat your purposes. If you overstuff them too severely you self compress the insulation. Not a good thing.
yeah, I think you nailed it. I dont believe you can realistically
reach 30° with a sewn 'thru baffle.
It would be pointless, it seems, to have anything more than a 1.5" loft if you have shells sewn together. That will give a fair rating of 40° alone. You could push it down to 30 with a bunch of clothing layers.
