Stacking underquilts?

Thanks all! This is helpful.
Any condensation concerns between the layers? I would think not, but not sure.

Depends on the expected temps. When you get too much below freezing, the dew/frost point will end up somewhere in the loft of your down. This means that the water pushing through your quilts will freeze before it gets out. This isn't too much of a problem unless you are out for long periods of time.

General consensus that the shorter UQ goes outside the longer UQ?
ie Phoenix outside Incubator inside?

I stack my 0* and 20* quilts and figure I can make it to -40
The 20 UQ is one size shorter than the 0 making the 20 fit very nicely inside the 0.
When temps reach 10f I start stacking the UQ's and TQ's around 0f. Last yr only got to -18f and was very very toasty
Condensation can always be of issue so in winter cold I prefer a Hot Tent to mitigate those issues....is just a extra 7lbs of pack weight.

I've stacked my Snugpak UQ ( 32°) with my Snugpak Cocoon ( 25°- 30°)and was plenty warm in the upper teens.

If stacking synthetic and down, I'd be curious whether the condensation would be heavier in the inside layer or the outer layer. All else being equal, I'd prefer the moisture in my synthetic quilt rather than my down.

I have stacked a 20 and a zero underquilts. They are both full length.
I put 20 closest to hammock
And zero on outside furthest from hammock.
The 20 will be compressed and will lose some insulative value while compressed but it will still insulate some.
The zero on the outside is not compressed and it does the bulk of insulating.

Underquilts of two different sizes have their own protocol and may or may not always be in the order I used.

Condensation collects on the outside layer.

I stacked my two 20° quilts and slept toasty warm in -13°F this past January. In testing, I found that I got better loft by putting the smaller (lighter) quilt on the outside. It didn't compress the down on the larger quilt as much as the larger quilt compressed the smaller one when reversed. Also, having the longer quilt on the inside made it easier to get a good seal on the ends.
