A downhole tool for isolating zones in a well, the tool including a mandrel, a sealing element disposed around the mandrel, and an upper cone disposed around the mandrel proximate an upper end of the sealing element. The tool further including an upper slip assembly disposed around the mandrel adjacent a sloped surface of the upper cone, a lower cone disposed around the mandrel proximate a lower end of the sealing element, a lower slip assembly disposed around the mandrel adjacent a sloped surface of the lower cone, and two element end rings. Further, the tool includes a first element end ring disposed adjacent the upper end of the sealing element and a second element end ring disposed adjacent the lower end of the sealing element, and two element barrier assemblies, each assembly disposed adjacent one of the two element end rings.
