Dainese Spartan 66 Leather Pants Dainese has taken the protective aspects of leather and combined them with the comfort of fabric in the Spartan66. Innovative and patented 2skin technology is used in construction to bring the biaxial elastic properties of S1 fabric to the mechanical qualities of the leather, to which it is laminated at the points that require greater strength. This also permits extreme mobility and peerless ergonomics for the best adaptation to different body forms.
