Baba Yaga is a Slavic trickster witch/ogress who lives in a house with chicken feet and rides around in a mortar and pestle.  She is known to either help or hurt those who encounter her.  Much like the character Baba Yaga, Baba Yaga Sock yarn is tough and built to last.  Bluefaced Leicester is a strong and durable fiber.  The long staple (or length) of the fiber adds extra strength and we like that for a sock yarn, because that means that long fiber helps protect against wear and tear as well as still being sock against the skin.  The nylon adds an additional amount of strength and wear resistance.  Like Baba Yaga, this yarn is quite ambiguous; you can use it for socks, shirts, shawls, or even bralettes and blankets.
