From the Spinneybeck Website:
Ducale Velour is an embossed, shrunken, grain sueded, aniline dyed leather. The velvet-like face of Ducale Velour is protected by an impregnated, soil-resistant treatment which shields the surface without disturbing the suppleness and luxurious drape of this elegant leather.
The special retannage given Ducale Velour assists in perfecting the hand of this leather, as well as preparing the material for the full, rich dye penetration it receives. Ducale Velour is dyed twice. The second bath deepens the color and further enriches this unique leather.
