Julius Oiled Leather Short Girth With Elastic Black/Black 24"Products made from oiled leather. Oiled leather means suppleness and durability. High quality vegetable oils are applied to the leather during the tanning process. This opens the pores of the leather and the oil penetrates deep under several layers. The result is a slightly memorized effect, which is particularly noticeable on brown leather. The special material creates an excellent grip on the saddle, especially on riding boots and chaps.
