The leather
Tanned in the USA, our full-grain, shrunken bison leather is dense, durable, and rich with character—each hide shows natural grain peaks and markings, telling its own story.
Shrinking the grain tightens the fibers for added strength, while the pull-up finish shifts from graphite to deep black with movement.
We pair it with Horween Tannery, a legendary leather known around the world for its softness, flexibility, and deep conditioning oils that allow it to mold to the body and last for years.
