    20* underquilt plus a 40* underquilt equals what? in temperature range?

    I think Shug addressed this but I cant find it...

    I'd say 0° conservatively.
    There's a table here, which is intended for topquilts.

    60 of course In reality it's approximately 0°
    Typically a 40° quilt has ~1.5" of loft and a 20° has ~2.5" that is ~4" of loft which is ~ 0° quilt?

    I think a 0° is typically 3.5" loft, but when stacking quilts you can probably expect a slight loss of efficiency due to either slight gaps between the quilts or slight compression of the quilt closest to the hammock.

    There's debate about which order to stack them. Put the warmer quilt closer to your body? Or put it on the outside to avoid compressing the quilt with higher loft?

    If one was full length and one was partial, I'd put the partial on the outside to avoid an air gap forming where the partial length quilt ends, if it were on the inside.

    Minus 10F, or a little less warm due to some inefficiencies of trying to stack 2 quilts.

    Very insightful, cmc4free, and Trailslugs joke outa sight!
    All my quilts are full length and if I stack 0* and 20* I put 20 closest to me and 0 on outside. I cinch em up tight to fight air gaps. Twenty gets compressed and zero stays fully lofted.

    If I was more talented, maybe could have both quilts fully lofted

    It's very possible some cordage extensions on the end(s) of the primary suspension might be needed, in order to avoid compressing the inner quilt. Most/all of my UQs fit properly with the primary suspension adjusted as loose as it will go, so in order to stack without any compression, I'd have to add a few inches of cordage to the primary suspension of the quilt that would go on the outside of the stack.

    It's probably impossible to not have at least a little bit of compression when stacking - unless you have an obvious gap between the quilts and that would be worse than a little compression.

    I've only stacked top quilts, a 20 and 40. It was a ridiculous puffball of down. Felt like I could have gone to -20°. Maybe more since my 0° alone was plenty down to -16°.

    Good point about compressing the UQ. It would definitely be a good idea to test the fit before actually doing this.

    I tried it years ago and it looked like a mess, but I think it would have worked just fine (don't over tighten ends like this)
