         8 . The glove of  claim 1 , further comprising a foamed inner polymeric layer disposed on an inner surface of the polymeric coating. 
     
     
         9 . A method of forming a glove, comprising:
 disposing a coagulant on a former;   applying at least one of a first polymeric composition on the former to form a coating;   disposing a plurality of raised features, comprising a second polymeric composition, onto the coating; and   heating the coating and the plurality of raised features disposed thereon to cure the coating and the plurality of raised features, forming a glove having enhanced grip properties.   
     
     
         10 . The method of  claim 9 , wherein the second polymeric composition of the plurality of raised features comprises polyurethane and the first polymeric composition comprising the polymeric coating includes nitrile-butadiene, and the polyurethane raised features enhance good wet and oily grip properties and the nitrile-butadiene enhance good dry grip properties. 
     
     
         11 . The method of  claim 9 , wherein the second polymeric composition of the plurality of raised features comprises nitrile-butadiene and the first polymeric composition comprising the raised features includes polyurethane, wherein the polymeric coating has enhanced good wet and oily grip properties and the plurality of raised features has enhanced good dry grip properties. 
     
     
         12 . The method of  claim 9 , wherein at least one of the first polymeric composition and second polymeric composition is foamed. 
     
     
         13 . The method of  claim 9 , wherein the disposing the plurality of raised features step is a screen printing step. 
     
     
         14 . The method of  claim 9 , wherein a second coagulant is disposed onto the coating before the disposing the plurality of raised features step. 
     
     
         15 . The method of  claim 9 , wherein at least one of the first polymeric composition or the second polymeric composition comprises natural latex, guayule, polyisoprene, synthetic latexes, butadiene, non-carboxylated acrylonitrile butadiene, carboxylated acrylonitrile butadiene, butyl latex, polychloroprene, acrylics, styrene-butadiene, acrylonitrile-butadiene, or blends thereof. 
     
     
         16 . A method of forming a multi-layer glove, comprising:
 disposing a coagulant on a former;   dipping the former into a first polymeric composition to form a first coating;   disposing a coagulant on the first coating;   dipping the former having the first coating disposed thereon into a second polymeric composition to form a second coating onto the first coating;   disposing a coagulant onto the second coating;   disposing a plurality of raised features onto the second coating; and   heating the first coating, the second coating, and the plurality of raised features disposed on the second coating to cure the first coating, the second coating, and the plurality of raised features, forming a multi-layer glove having enhanced grip properties.
