A light weight insulating sheet comprised of down insulation mixed with polymer fibers is described. The down and polymer fibers provide improved stretchability and lofting as well as improved drying of the insulating material. The polymer fibers may be polyester or crimped lofting fibers and these may be mixed with micro fibers to further improved lofting. A binder may be added in the form of a powder glue of be constituted by the polymeric fibers such as when subjected to heat the glue binds to the mixture or the fibers interconnect at their crossings binds the mixture. |
