Horween Leather Company — The Family Tannery Behind America's Toughest Leather

August 24, 2026

Some leather comes from massive, anonymous industrial factories.

This leather comes from one family, working in one building in Chicago — and they've been doing it for over 100 years.

That is the story of Horween Leather Company.

1. How It Started

In 1905, Isidore Horween started a small leather workshop in Chicago.

Having emigrated from Ukraine years earlier, he learned the leather trade from the ground up.

Today, the company still operates from Chicago, run by the very same family — now five generations later.

2. From Razor Strops to Heritage Footwear

At first, Horween didn't make leather for boots, bags, or watch straps.

They made razor strops — leather strips used to sharpen straight razors.

When safety razors gained popularity, demand for strops dropped, forcing Horween to pivot.

They began producing high-grade shoe leather, quickly earning a reputation for exceptional durability and character.

3. Shell Cordovan: The Six-Month Leather

Shell Cordovan is the leather Horween is most famous for globally.

It doesn't come from cowhide; it is crafted from a dense, fibrous membrane beneath the hide of a horse's hindquarters, known as the "shell."

Producing Shell Cordovan takes approximately six months of slow, vegetable tanning using natural tree barks rather than harsh industrial chemicals.

Horween remains one of the very few tanneries in the world still making genuine Shell Cordovan — and is widely considered the absolute benchmark.

4. Chromexcel: The Everyday Icon

While Shell Cordovan gets the fame, Chromexcel is often the leather enthusiasts wear most.

It is a rich, heavily oiled combination-tanned leather renowned for its "pull-up" effect — the color lightens temporarily when bent or stretched, as natural oils shift within the hide, then gradually settles back.

Bootmakers and watch strap makers prize Chromexcel for its supple feel, immediate comfort, and rugged patina potential.

5. Built Where Toughness Matters

Horween doesn't only craft leather for fine footwear and watch straps.

They also produce specialized, heavy-duty leather used for official NFL footballs.

While the product requirements are entirely different, the standard of craftsmanship remains identical: built to handle abuse and made to last.

6. The Last Tannery Standing in Chicago

Chicago was once home to dozens of tanneries along the river.

Over the decades, almost all of them closed or relocated overseas in search of cheaper production.

Horween stayed.

Today, it stands as the last remaining tannery in Chicago — sticking to traditional, slow tanning methods in a world that constantly demands speed.

HMS Tip 💡

Look for named leathers like Horween Shell Cordovan or Horween Chromexcel.

When a watch strap uses genuine Horween leather, a maker will state it clearly by name. Provenance gives you confidence in how the leather will break in and age over time.

At HMS, we name our tanneries and leathers because a watch strap should carry a verifiable story.
