What is claimed is: 1. An elastomeric article having wet and dry donnability, said article comprising: a substrate body including a layer made of an elastomeric material, said substrate body having an inside surface and an outside surface; a donning layer overlying the inside surface of said substrate body, said donning layer being formed from a water-soluble polyurethane, wherein said donning layer is halogenated; and a lubricant that coats and contacts the donning layer, said lubricant being formed from a silicone emulsion, said lubricant having a thickness from about 0.001 millimeters to about 0.4 millimeters. 2. An elastomeric article as defined in claim 1, wherein said water-soluble polyurethane is formed by reacting a polyurethane prepolymer with a chain extender. 3. An elastomeric article as defined in claim 2, wherein said prepolymer is formed by reacting a polyisocyanate with a polyol. 4. An elastomeric article as defined in claim 3, wherein said polyol is a polyester polyol. 5. An elastomeric article as defined in claim 3, wherein said polyisocyanate is an aliphatic polyisocyanate. 6. An elastomeric article as defined in claim 3, wherein a water-solubilizing compound is further reacted with said polyol and said polyisocyanate to form said polyurethane prepolymer. 7. An elastomeric article as defined in claim 2, wherein said chain extender includes an organic amine, inorganic amine, or combinations thereof. 8. An elastomeric article as defined in claim 1, wherein said water-soluble polyurethane has a solids content of from about 1 weight % to about 10 weight %. 9. An elastomeric article as defined in claim 1, wherein said donning layer has a thickness of from about 0.5 micrometers to about 20 micrometers. 10. An elastomeric article as defined in claim 1, wherein said donning layer has a thickness of from about 1 micrometer to about 5 micrometers. 11. An elastomeric article as defined in claim 1, wherein said silicone emulsion contains a polysiloxane having at least one functional group selected from the group consisting of amino, carboxyl, hydroxyl, ether, polyether, aldehyde, ketone, amide, ester, thiol groups, and combinations thereof. 12. An elastomeric article as defined in claim 1, wherein said silicone emulsion has a solids content of from about 0.1 weight % to about 10 weight %. 13.

An elastomeric glove as defined in claim 18, wherein the elastomeric material of said substrate body is natural rubber latex. 25. An elastomeric article as defined in claim 1, wherein said donning layer has a thickness of from about 0.5 micrometers to about 10 micrometers. 26. An elastomeric article as defined in claim 1, wherein said donning layer has a thickness of from about 1 micrometer to about 10 micrometers. 27. An elastomeric glove as defined in claim 18, wherein said donning layer has a thickness of from about 0.5 micrometers to about 10 micrometers. 28. An elastomeric glove as defined in claim 18, wherein said donning layer has a thickness of from about 1 micrometer to about 10 micrometers. 29. An elastomeric article as defined in claim 1, wherein said water-soluble polyurethane is carboxylated. 30. An elastomeric article as defined in claim 29, wherein said water-soluble polyurethane is a carboxylated aliphatic polyester polyurethane. 31.
