What does it mean for a yarn to be "Sock"

A wool called SOCK, is a mixture of 75% wool and 25% polyamide (nylon), especially recommended for knitting socks due to its composition and resistance.

They exist in different thicknesses but it is mainly manufactured in fingering thickness.

Although its name is Sock (sock), our wool is so soft that it can be used for any type of garment, be it a sweater, shawl, baby garment, whatever you prefer.
