A combination of fine-grain leather, velvety nubuck and robust stretchy elastane.
Apply a compatible water/stain protector before wearing and after each clean. For regularly cleaning nubuck, use a suede brush moving in the same direction to remove dust and dirt and a gum eraser for any scuffs. Avoid wax polish as this will spoil the special finish. Use a soft dry cloth on smooth leather. If dampened allow leather to air-dry naturally away from direct heat.
