man. that's actually pretty interesting looking

whether it's feasible or not, be neat to try

My guess is the R-Value is probably on the lower (and cheaper) side to cover the spring / fall but not the winter. It would be miserable to use winter insulation in the summer and it's a costly endeavor for a start-up.
I'm happy with my setup, which is more versatile: summer, spring/fall, and winter as needed. I've never used a double-later with a pad, but maybe one day I'll give it a shot.
