This is false, it's a mix, other houses sell vicuna sweaters, in fact you can buy them from unknown sources, even the raw material itself and have someone knit it for you, it is extremely expensive however you acquire it. The house adds value to the material, as with any high-end producer like Brunello, Zegna, and the next one to pop-off Rubinacci (watch this space).
