A medical bandaging product that includes a flexible medical material including an elongate fabric, a reactive system, and microspheres. In certain aspects, a component of the reactive system is homogeneously impregnated into or coated throughout the flexible medical material without being encapsulated in the microspheres such that the reactive system remains stable and non-activated in the absence of an activating agent, and hardens upon activation by exposure to the activating agent to form a rigid, self-supporting structure. In this aspect, the microspheres are homogeneously impregnated into or coated throughout the flexible medical material, the microspheres encapsulate an activating agent and are configured to release the activating agent to form the rigid, self-supporting structure.
