In addition to our fully finished top-grain cowhide we offer a semi-naked cowhide that we call JET, showcased in Chapter 17. In contrast with our traditional leather, JET is not stuffed with waxes and is only semi-polished. Though still durable, JET is soft and its finish is more fragile which means that over time some fading is possible from UV degradation of the dyes. The benefit of Jet is that it is more supple, like a nude leather, but with better wear characteristics than nude hides. 
We also offer a top grain horsehide in two finishes. The black horsehide is fully finished like our top-grain cow. The brown and tan horsehides are oil-stuffed and ironed to create a unique "living" leather that changes in tone as the jacket moves. Horsehide can be seen in chapter 16.
Why horsehide? Everyone who remembers Granddad's leather jacket remembers it in horsehide and if that's the way it used to be then it must be better, right? Not necessarily. Granddad's jacket was made of horsehide primarily because in his day there were more horses around used for drayage and agricultural purposes. Horsehide, though more expensive than cowhide, is not necessarily more protective. It is unusual and it is nostalgic and evocative of another era and, though perfectly functional as a daily-driver motorcycle jacket, its price is more representative of its exclusiveness and is not relative to any inherently greater protective qualities.
