GGH Esprit Yarn, or any other super soft yarn

Hello. I'm looking for a discontinued yarn. It is GGH Esprit yarn. I really don't care about the color. Also I don't know that much about the different yarns, but I'm looking for the softest fuzzy like yarn I can find. I am going through chemo and need some to knit some hats for myself. If any one can suggest a very soft yarn I would really appriciate it. Thank you very much. Teresa.
