It is based on a 1960s knit cardigan from a long-established Austrian manufacturer founded in the late 19th century.
This manufacturer is said to have brought knitting techniques from England.
It is a very tightly knit garment, and the seamless shaped knitting continues all the way to the folded neckline, which requires extremely advanced techniques.
The yarn is made from a blend of fine merino wool and WEANERS wool, which is a cross between lamb's wool and adult sheep's wool, giving it the flexibility of lamb's wool and the elasticity of adult merino wool.
