“I'm open to two bags or even quilts, but have not seen any that make sense from a price or weight perspective when you have to carry two.”

My favorite quilt is my zpacks 20F quilt (single person). It’s my warmest quilt. So I’ll put a plug in for the double. It’s lighter and cheaper than the Spoonbill, and may be just as warm. http://www.zpacks.com/quilts.shtml The 20F twin quilt is 27oz and the 10F quilt is 31oz.

I’d prefer the twin quilt. However, right now my wife and I share one Western Mounatineering Megalight. She bought a mating zipper and sewed it too a very light fleece blanket (shape of a Cutie Pie)--- which happens to be a good ground insulator. Together it weighs 33oz. On cold nights, the Megalight is on both of us. On warm nights, we flip it over. It so happens the zipper also mates with our WM Caribou and Antelope GWS.

Let us know what you do.
Thanx,
