Foil Foam Foil 5mm insulation

[BIG-E]

I have found something similar and a whole lot cheaper, windsheild reflectors from the dollar store. They work great as an addition to the underquilt in sub 20 degree nights.

Purchased last late summer from the local Ace Hardware for less than $20. Smallest roll they stocked. Only needed chunks to make pot and freezer bag cozy. Was thinking about using as an underpad insulation. But at ~13oz for the remaining ~70" it's a bit heavy compared to the HH ocf+sb combo which works fine for me down to at least 40F.
