Full grain leather uses the best parts of the hide. Nubuck is a full grain leather that has been gently brushed to give the surface a different character. The Nubuck surface breathes better and is easier to re-impregnate. The leather is impregnated directly at the tannery and no fluorocarbons are used in the process, which takes place in a closed system. Thicknesses of 2.0–2.2 mm.
