Vicuña.

With an average diametre of 12-13 microns, Vicuña fibre has an incomparable thermo-regulating power. Still sheared today with the same methods of the past, Vicuña is regarded as the finest animal fibre in the world with extraordinary characteristics of lightness, softness and resistance. The adult Vicuña produces only 100 grams of wool every two years and the intrinsic value of a fabric or garment made in Vicuña is increased further by the fibre rareness and authentic art of processing it.
