I am preparing for a late fall trip in the hills of Tennessee and as I'm evolving my gear I have started looking for an under-quilt. I am strongly considering the Hammock gear econ incubator but if the standard incubator is miles ahead of the econ I will pay the extra. Does anyone here use either of these under-quilts? Or can anyone recommend another under-quilt around the 200 dollar range? More expensive quilts would be difficult because I'm buying two, one for me and one for my wife.
