Often just called "buffalo" in the US, but it's American bison hide — a different animal from true water buffalo.
Bison leather comes from the American bison — sometimes called "the original American leather" for being a native species rather than an import. It has a distinctive wrinkly, pebbly grain and a denser hair follicle structure than true buffalo, which shows up as finer, tighter texture. Side by side with cowhide of the same weight, bison tends to run marginally thicker and the tanning process stretches it less, but in practical grain and durability testing the two perform comparably — the tannage matters more than which animal it came from.
Western boot uppers, where bison's rugged, heavily grained look does a lot of the work — it reads as a tougher, more rustic alternative to cowhide without actually outperforming it by much. The appeal is as much the all-American provenance and distinctive texture as any real durability edge.
Bison dries out faster than cowhide, so it benefits from more frequent conditioning — Leather Honey is a commonly recommended all-around option for it. Otherwise, standard leather care applies; see our boot care guide.
