Vegetable tanning is the traditional leather processing method that uses natural plant-based tannins rather than synthetic chemicals. It produces the firmest, most structured leather — the type historically used in quality American motorcycle gear.

Full-grain leather is the highest quality leather grade — it retains the complete outer grain of the hide, which contains the strongest, most durable fibers. Understanding full-grain leather is essential for any rider evaluating motorcycle jackets, gloves, and vests.

Deerskin is the tanned leather made from deer hides, and the preferred material for premium American motorcycle gloves. Its unique fiber structure provides extraordinary softness combined with natural moisture resistance, abrasion resistance, and a fit that molds precisely to the hand.

Horsehide is the tanned leather made from horse hides, and the standard material in American motorcycle jackets from the 1930s through the 1960s. Learn what makes horsehide different from cowhide, why it is scarce today, and why it remains the gold standard for serious riding jackets.
