21 microns is the unit of measurement of a specific choice of style, which gives the fabric durability, crease resistance and the perfect drape, as well as a dry, energetic hand. These are unique qualities of which the secret is the materials at their heart: the deliberately thicker wools, full-bodied, stretchy and sensitive, and of Southern American origins. The ASCOT collection includes three different weaves of great elegance and versatility, in two, four and even six ply, produced by the Vitale Barberis Canonico wool mill.
