Can You "Nest" 2 Top Quilts?

[cmoulder]

If I have a 50 degree synthetic and a 30
Degree down, which one would you put on the outside? Why?

Synthetic on the outside... far better to get condensation/frost on synthetic than down.

It depends on the situation but 90% of the time I would go synthetic on the outside because sounds like you are trying to hit colder weather capabilities and your breath condensation on the synthetic quilt will have little to no effect on its ability to trap air whereas the down will begin to compress and wilt inside when wet which will decrease its effectiveness at trapping air. You will get colder with a moist down quilt.

My thought would be the down would compress more if under a synthetic quilt rather than stay lofted if on top...

At the end of this vid I talk about stacking TQ's.

I don’t think a light quilt like a 50* synthetic would compress a down quilt very much, if at all. The heavy quilt on top would most likely cause more compression. Anyway, I’d still do synthetic on outside for aforementioned reasons. HYOH

Just wondering if it's possible (and actually usable) to nest 2 top quilts together for winter use?

I've experimented with this type of setup but haven't quantified the results. I have a poncho liner to which I added a drawstring so I can make a sort of faux footbox. I've used the poncho liner inside my Hudson River down quilt and slept quite warm, but the temps only dropped to mid-20s the night I tried it, so I haven't plumbed the depths of what it might do. My initial thought was that the synthetic liner should be on the inside to avoid compressing the down in the top quilt, but questions of condensation brought up by others in this thread may make me reconsider.

Several years back, I used something similar but the other way around, wrapping the poncho liner on the outside of my other insulation. At that time I was using a synthetic sleeping bag and found the poncho liner definitely helped. It worked even better as a pod system wrapped around the entire hammock with me in the sleeping bag, but it was a pain to get in and adjust things.

The only data point I can offer is that I layered a 50deg Revelation with a 40deg Prodigy (now called Revelation APEX) and was good down to 14°F. (That was a ground setup with Xtherm and 3/8" CCF on top of the Xtherm.)

I modified the elastic straps in this photo to join the quilts, but EE also sells them pre-made.

To add to the discussion, I just had a 40 and 20 stacked down to -5* F and it was plenty warm. I go back and forth on having the 40 on the inside or outside. With it inside I get better draft control and feel like I'm cocooned in down. It's probably best served on the outside for maximum loft though. The 20 has a sewn footbox and the 40 is a drawcord with no taper on the length.

Edited to add the TQ's are 55" wide and the outer quilt isn't as stretched as the picture may look. I had the head end cinched down but there is plenty of room for the inner quilt throughout.

Tonight I'm stacking my 40° Burrow and 35° overstuffed CDT TQ on top, and underneath my Snugpak UQ and new SLD Trail Winder 40° asym UQ/UQP. Should get into the mid to high teens so I'll be plenty warm enough with this setup!

I put a 50 inside a zero and was warm in a 30 below night. There was a bit of wrangling whenever I rolled over but nothing unexpected.

I nested 20* and 0* top quilts
First I put one foot and leg into one top quilt
Then I put same foot, leg and original top quilt into second top quilt
Now they are both nested and only one foot, leg is inside of both nested
Then I put my other foot, leg inside nested combo

If overheating (a little warm), I push Only the top half of outermost quilt off edge of hammock, while keeping the bottom footboxes nested and both feet inside.
YMMV, might work for you and might not...
