Camping right before Halloween in what I expect will be 30s (or worse) at night.

I have a 40-degree full-length underquilt and a 20-degree shorter underquilt (both Hammock Gear).

Since it's car camping, I figure I'll try using both, with the full-length one directly under the hammock and the other quilt under that.

I expect cinching the top underquilt will be the most important; the one under it is to provide some supplemental toastiness.

What do y'all think? TIA
