1. A composite fabric, comprising:
a film having a first side and a second side;
a first fibrous layer having a first side facing the second side of the film and a second side;
a fabric layer having a first side facing the second side of the first fibrous layer and a second side;
a second fibrous layer having a first side facing the second side of the fabric layer and a second side; and
a plurality of retaining members extending from the second side of the second fibrous layer and configured to contact a surface on which the composite fabric is placed and to space at least a portion of the second side of the second fibrous layer from the surface, wherein the retaining members and the first fabric layer each include a first vapor corrosion inhibitor within the plurality of retaining members and the first fabric layer configured to vaporize and collect between the surface and the portion of the second side of the second fibrous layer spaced from the surface wherein the plurality of retaining members and the second side of the second fibrous layer are configured to cooperate with the surface to form at least one pocket configured to retain the vaporized first vapor corrosion inhibitor therein, and wherein the plurality of retaining members are configured such that movement between the plurality of retaining members and the surface facilitates release of the first vapor corrosion inhibitor from the plurality of retaining members.
