SYSTEMA NATVRAE® is the pièce of résistance of Cariaggi Fine Yarns Collection, it is the result of a long research and development project to dye cashmere.  Systema Natvrae colors are exclusively obtained from medicinal herbs, flowers, leaves, berries and roots that can be used as dyes. This is genuine, "slow" dyeing, a procedure from days gone by that has beem made contemporary, modern and technological. The end result is a unique and unconventional color palette inspired by the tapestries of the 16th century and by the many masterpieces of Italian textile art. The handcrafted quality that is achieved, the uniqueness and chromatic beauty of the dyes and the vibrant and harmonious reflection of light on the yarn are all intrinsic features of SYSTEMA NATVRAE® cashmere making it even more recognisable, authentic and exclusive.
