Claim:
A medical bandaging product, comprising: (a) a sleeve of a predetermined length formed of a moisture-impervious material and sealable to prevent entry of moisture; (b) a medical material positioned within the sleeve in substantially moisture-free conditions and sealed therein against moisture until use, said medical material comprising: (I) a warp-knitted substrate having a pair of opposed, major surfaces, said substrate being constructed of both elastomeric and inelastic yarns, wherein the elastomeric yarns are present in the warp direction only to provide the substrate with a predetermined extensibility and wherein the elastomeric and inelastic yarns each have about 48 to about 90 filaments; and (ii) a reactive system impregnated into or coated onto said substrate, said system remaining stable when maintained in substantially moisture-free conditions and hardening upon exposure to sufficient moisture to form a rigid, self supporting structure.
