Schott Bros. NYC is an apparel company that is headquartered in Union, New Jersey, and has been around for over 100 years.

Its flagship product, the leather motorcycle jacket, has been worn by everyone from Marlon Brando to Bruce Springsteen.

Business Insider got a peek inside the New Jersey factory to see how they've been manufacturing the coolest apparel for decades.

Schott Bros. NYC is more than just a jacket-making company. It's a legacy — one that's been manufacturing jackets worn by some of the coolest people of the last century. The company, which was started in 1913 by Irving Schott on New York City's Lower East Side, invented the motorcycle jacket in 1928, and it's been hand-sewing the jackets in the same way ever since.

Everyone from Marlon Brando and James Dean to the Ramones and Bruce Springsteen have donned Schott's Perfecto jacket, or a slight modification of it. The company also manufactures other apparel, including peacoats, shirts, and shoes for men and women.
