I recently picked up a Nest from a member of the forum and I just ordered the 3-season quilt sent from Jacks R Better for when I hang with my son.

Questions is if anyone has tried doubled up Nests. I was thinking that for my solo winter trips I could use both Nests as under-quilts for those very cold nights. I know it is very subjective, but (leaving top insulation out of it, there are a lot of options there) how low do you think the temp could go and still stay warm?
