Spididenim Racer, the "red leather label". Its internal structure is so sophisticate that it is even suggested to fast riders. In addition to leather and Keramide protections for knees, we lined the back with technical material, while critical areas such as knees, back pockets and hips have been reinforced through multiple double stitches. Comfort under the rain is guaranteed by Schoeller NanoSphere®water-resistant treatment.
