After some not so deep thinking, the idea of a reflectix underquilt happened upon me. If I created an under quilt made entirely of on layer of reflectix, would it work? Has anyone ever tried? It would seem to me that would be quite cost-effective. Would I have to double up or be in for a cold night and a chilling sleep?
