Elixir Strings with the Polyweb coating have the warm tone and smooth action of non-coated strings, yet they feel softer to the touch. The ultra-thin Polyweb coating keeps these strings sounding fresh and new for a lot longer than conventional strings. The Ployweb coating cuts down on finger squeak while reducing the bite of the strings on your fingers. They have a mellow and warm tone, and maintain their original sound and feel longer than most strings.
