Snaps

What is a pearl snap shirt? The snap and its history

A pearl snap shirt is a western shirt that closes with snap fasteners instead of buttons, each snap capped with a pearl-look insert. The New York Times credits Jack A. Weil of Rockmount as almost certainly the first to put snaps on Western shirts. Real mother-of-pearl cracked in laundering, so synthetic inserts took over by the '50s.

What makes a shirt a pearl snap

A pearl snap shirt is a western shirt whose front closes with snaps, and whose snap caps carry a pearly insert.

Everything else about the shirt can change. The cloth can be cotton, Tencel, denim or a stretch polyester. The yoke can be pointed or curved, and the pockets can be sawtooth flaps or smile pockets (the anatomy guide draws each one). What earns the name is the hardware.

Why do western shirts use snaps?

Snaps let go under a hard pull.

The New York Times put it plainly in its 2008 obituary of Jack A. Weil: snaps "break loose easily if the shirt is caught on a hostile horn." Rockmount's own history says the same about a bull's horn, and Steve Weil told Cowboys & Indians the snap also helps if the shirt snags on a tree branch. He added a second reason in the same interview: "What cowboy wants to sew his buttons back on?"

A 2016 Cowboys & Indians profile of Panhandle Western Wear gives one more, smaller advantage. A snap shirt can be opened and closed one-handed.

Who put snaps on western shirts first?

The best-sourced answer is Jack A. Weil, who founded Rockmount Ranch Wear in Denver in 1946.

The Times called him "almost certainly the first to put snaps on Western shirts (17 on a shirt)." The same obituary says that once the metal shortages of World War II were over, he made diamond-shaped metal snaps, often with mother-of-pearl covers, and built the new business on them. Rockmount still names the diamond snap and the sawtooth pocket as its signature design.

Other brands tell their own story. Panhandle Slim, also founded in 1946, describes itself on its about page as "the creator of the pearl snap shirt." The 2016 Cowboys & Indians piece on that same company credits Weil with the snap closure, so this guide follows the Times.

Are the pearls real?

On current shirts, almost never. Steve Weil said the first Rockmount snaps in the '40s had no pearl at all. A few years later the company tried real mother-of-pearl, which cracked when the shirts went through a laundering press, and by the '50s it had moved to synthetic inserts "which are still used today."

That history explains the wording on modern listings. Tecovas says "faux horn pearl snaps." Scully, sold at Pinto Ranch, says "pearlescent diamond snaps." Neither claims shell.

How do retailers describe the snaps?

Listings use a short closure line, and it is the most useful clue to what the snaps look like. The table below copies that line from five current shirts. Shape varies more than most shoppers expect: Stetson puts turquoise hexagon snaps with copper rims on a women's denim shirt, while Cinch lists white marble snaps on a cotton herringbone. For a set of shirts picked around the closure, see the pearl snap roundup.
