1. An insulated shipping and/or storage bag having a bottom, walls, and an opening generally opposite the bottom, wherein the bag is configurable between a bag configuration and a free standing configuration capable of maintaining a supporting shape when placed on a surface, the bag comprising: an outer layer;an intermediate layer, said intermediate layer being made from an insulating batt of single sheet of material having a generally rectangular shape with cut outs at each of four corners thereof and opposing cut outs generally centrally along opposite side edges of said sheet of material so as to form a middle portion between two side portions each having an end portion on an end opposite said middle portion, said cut outs enabling a free standing configuration whereby said intermediate layer is folded centrally thereof so that said middle portion becomes the bottom, said side portions become the walls, and said end portions cover the opening of the bag and whereby said intermediate layer continuously extends along the bottom and walls and covers the opening of the free-standing configuration of the bag without overlap of said intermediate layer; andan inner layer that is configured to form an article receiving pouch, said inner layer including a cuff in which said end portions of said intermediate layer are received to thereby secure said intermediate layer to said inner layer and to create a seal separating said intermediate layer from the interior of the bag, wherein in the free standing configuration of the bag, said cuff extends over said end portions and along at least a portion of an outer surface of said intermediate layer. 2. The insulated shipping and/or storage bag of claim 1 wherein the inner layer is made of paper. 3. The insulated shipping and/or storage bag of claim 1 wherein the inner layer is made of Kraft based film. 4. The insulated shipping and/or storage bag of claim 1 wherein the insulating batt of the intermediate layer is comprised of a combination of natural fibers. 5. The insulated shipping and/or storage bag of claim 1 wherein the insulating batt of the intermediate layer includes a lofting fiber including one or more of polypropylene, polyester, jute, kenaf, flax, hemp, wool, and cotton. 6. The insulated shipping and/or storage bag of claim 1 wherein the insulating batt of the intermediate layer includes: a. a lofting fiber including one or more of polypropylene, polyester, jute, kenaf, flax, hemp, and cotton; andb. a bi-component binder fiber with low-melt sheath and core, the binder fiber is selected from polylactic acid (PLA), an activated copolyolefin sheath and a polyester core, a copolyester sheath and a polyester core, a crimped fiber with a copolyester sheath and a polyester core. 7. The insulated shipping and/or storage bag of claim 1 further comprising venting means to vent air from between said inner layer and said outer layer to permit the shipping and/or storage bag to be compactly configured for shipment to an end user without allowing air to enter the interior of the bag. 8. The insulated shipping and/or storage bag of claim 7 further comprising covering means for covering said venting means. 9. The insulated shipping and/or storage bag of claim 1 wherein said intermediate layer is between approximately one half inch to one and one half inches in thickness. 10. The insulated shipping and/or storage bag of claim 1 wherein said sheet of material further includes slits extending inwardly from each of said cut outs. 11. The insulated shipping and/or storage bag of claim 1 further comprising sealing means for sealing the opening into the bag. 12. The insulated shipping and/or storage bag of claim 11, wherein said sealing means includes a handle. 13. The insulated shipping and/or storage bag of claim 1, wherein said outer layer is made of paper. 14. The insulated shipping and/or storage bag of claim 1, wherein said outer layer is made of Kraft based film. 15. The insulated shipping and/or storage bag of claim 1, wherein a portion of said cuff extending along at least a portion of an outer surface of said intermediate material layer is secured to an inner surface of said outer layer of the bag.
