Paul McCartney. Elvis. Martha Stewart. Those are a few celebrities who’ve worn the iconic Western shirts designed and created by Jack A. Weil, known as “Papa Jack,” the founder of Rockmount Ranchwear.
Featuring pearl snap buttons, two pockets, wide cuffs, and a style-forward design, Papa Jack’s “Diamond” shirts went on to define an era of Western fashion and make his business, Rockmount Ranchwear, one of Denver’s most successful.
The store still occupies the same space on Wazee Street as it has for decades. They still sell shirts inspired by the same design. They’re still made in the USA.
So what has changed? Since Papa Jack passed away in 2008 at the age of 107, his great-grandson, grandson, and son have all become involved in the business. They have an online store in addition to being sold at retailers worldwide.
Most importantly, though, the original goal of Rockmount Ranchwear remains the same. That mission is to not only sell Western clothing, or even the idea of a cowboy — but to sell the lifestyle of the West in a totally different way.
As Steve Weil, Papa Jack’s son, puts it: "Papa Jack didn't just create a new kind of shirt, he started a whole new fashion. He gave those who identify with the American Western way of life a style tailored specifically for them.”
