Zipper

You probably use a zipper every day without giving it a second thought. But behind that simple pull lies a surprisingly complex history of failed patents, accidental branding, and engineering that's traveled from ocean depths to outer space. The zipper's story is stranger and more fascinating than you'd expect. Stick around — what you're about to discover might change the way you look at your jacket forever.

Key Takeaways

• The word "zipper" was coined by B.F. Goodrich in 1923, derived from "zip," an onomatopoeic word mimicking the sound of closure.
• Whitcomb Judson invented the first zipper prototype, called the "Clasp Locker," debuting it at the 1893 Chicago World's Fair.
• Zippers were largely confined to footwear and tobacco pouches for nearly two decades before expanding into mainstream clothing.
• Apollo mission spacesuits used two zippers with a rubber layer between them to create airtight, life-preserving seals.
• French designers declared zippers superior to buttons for men's trousers in 1937, dramatically accelerating mainstream fashion adoption.

Who Really Invented the Zipper?

The story of the zipper's invention isn't as simple as crediting a single person. You'll find three key figures shaping its history. Elias Howe Jr. patented a garment fastening in 1851, but the Howe controversy stems from his device resembling a drawstring rather than a true zipper. He abandoned the idea, chasing sewing machine success instead.

Whitcomb Judson's legacy grew from his 1893 "Clasp Locker" patent, designed to replace shoe buttons. Though he debuted it at Chicago's World's Fair, the device kept pulling apart, limiting its appeal. Much like Pablo Picasso's Guernica, which used stark imagery to convey a powerful message to a wide audience, Judson's invention captured public attention despite its practical shortcomings.

Swedish-American engineer Gideon Sundback ultimately solved the problem. By increasing interlocking teeth to 10 per inch and patenting his "Separable Fastener" in 1917, he created the reliable zipper you recognize today. In 1923, Sundback sold the rights to Martin Othmar Winterhalter, who further refined the design by adding ribs and grooves to the teeth.

The name "zipper" itself came from the rubber industry, when B. F. Goodrich coined the term in 1923 to describe the zip sound the fastener made on their rubber boots.

How Did the Zipper Get Its Name?

Tracing the zipper's name back to its roots, you'll find B.F. Goodrich Company coined the term in 1923. They applied a sliding fastener to rubber galoshes and branded them "Zipper boots," making boot marketing central to the name's origin. The word itself came from "zip," an onomatopoeic term capturing the sharp, quick sound the fastener made during closure. This sound branding strategy proved brilliant—the name was memorable, distinctive, and descriptive all at once.

Before Goodrich's branding, people called the device a "clasp locker" or "separable fastener." Neither stuck. "Zipper" did. Public adoption quickly transformed it from a brand name into a generic term. While North Americans say "zipper," the British prefer "zip fastener," but both trace back to that same 1923 boot campaign. Despite its eventual success, the zipper took nearly 70 years to be fully perfected and achieve widespread adoption after its initial development.

The zipper's core mechanism relies on a slider containing a Y-shaped channel that meshes or separates teeth depending on the direction of movement, making the satisfying "zip" sound all the more fitting for what the device physically does.

What Are the Parts That Make a Zipper Work?

Every zipper relies on five key parts working together: the slider, teeth, tape, top stops, and bottom stops. The slider travels along the zipper, using its internal mechanism to join or separate the teeth. Regular slider lubrication keeps it moving smoothly and extends its lifespan.

The teeth—made from plastic, coil, or metal—interlock to form a secure chain. The tape, typically polyester, holds everything in place and undergoes durability testing to make certain it withstands repeated stress.

Top stops prevent the slider from pulling off the end and you can add them to continuous zipper chains. Bottom stops and separating parts, including the starter box and insertion pin, are exclusive to jacket-style zippers, preventing over-opening and allowing full separation. A zipper can also serve as a decorative design element, depending on whether it is visibly showcased or concealed within the garment.

Zippers are used across a wide range of applications, from everyday items like jeans and backpacks to specialized uses such as providing an airtight seal in spacesuits.

Where Did Zippers First Appear in Everyday Life?

Although the zipper seems like a timeless staple today, its path into everyday life started narrowly—with shoes. Whitcomb Judson originally designed his clasp locker to replace boot buttons, and B.F. Goodrich later applied the technology to rubber galoshes, creating the first mass-market success in 1923.

For nearly two decades, zippers stayed largely in footwear, with tobacco pouches serving as a secondary use. You'd have seen few zippers anywhere else during that stretch.

That changed in the late 1920s and early 1930s, when manufacturers introduced zippers onto children's overalls and similar garments. Marketers promoted them as tools for independence, letting kids dress themselves. This shift into children's clothing set the stage for zippers eventually moving into adult everyday apparel throughout the 1930s. Plastic zippers became bold visible design statements when Elsa Schiaparelli incorporated them into her landmark 1935 winter collection. The 1938 Schiaparelli–Dalí collaboration took this further, producing the iconic skeleton dress with large plastic zippers featured on the shoulders and right seam.

How Zippers Transformed Fashion From Buttons to Runways

The zipper's rise in fashion didn't happen overnight—it started with a single debate. In 1937, French designers declared zippers superior to buttons for men's trousers, shifting fashion's course permanently. That victory pushed zippers beyond footwear and into everyday clothing.

For women's garments, invisible zippers became standard after 1937, making dresses easier to wear across formal, casual, and sports settings. They transformed how designers constructed garments—smarter and simpler. Designers soon began placing zippers on sleeves, necklines, and dress fronts as visible decorative features, marking a bold shift from function to fashion statement.

Zipper pulls and sliders were eventually embraced as branding opportunities, allowing designers to turn a once purely utilitarian component into a recognizable signature of their label's identity. This mirrors how Andy Warhol used silk-screening techniques to blur the lines between commercial design and fine art, challenging traditional notions of what could be considered a legitimate creative medium.

From Spacesuits to Scuba Gear: Where Zippers Work Hardest

Fashion runways proved zippers could handle style, but some environments push them far beyond aesthetics. When you examine spacesuit seals on Apollo missions, you'll find two zippers working together with a rubber layer between them, creating an airtight barrier against vacuum conditions. That design kept pressure intact where failure meant death.

China's Shenzhou missions took zipper reliability even further. Engineers boosted tensile force from 760 to 2,000 newtons across nine missions, testing every detail over 100 times to eliminate any risk of jamming during critical operations.

Scuba closures face similar punishment underwater, where pressure and water intrusion constantly threaten gear integrity. Whether you're orbiting Earth or diving deep, these zippers aren't accessories — they're engineered lifelines holding your environment together under extreme conditions. The Apollo suit's inner zipper pull string presented a potential leakage path where it passed through the rubber sealing bands between the two closures.

In contrast, everyday invisible zippers are designed for far gentler applications, where their lightweight fine plastic coil makes them ideal for bridal gowns and formal garments but wholly unsuitable for high-stress environments like those faced by astronauts or divers.

Metal, Plastic, or Coil: How Zipper Types Differ

Zippers aren't one-size-fits-all — coil, plastic, and metal each solve different problems depending on where and how hard they're used.

Coil zippers use a continuous nylon or polyester strand stitched onto tape, making them the best flexible closures for curved seams, dresses, and activewear. In any weight comparison, coil runs 30–60% lighter than metal, which matters in performance gear.

Plastic zippers feature molded, interlocking teeth — stronger than coil and ideal for jackets and heavy outerwear, though they handle curves poorly. Their teeth are molded directly onto the zipper tape rather than sewn, but they have a tendency to pull apart while closed, making them a poor choice for bags or luggage.

Metal zippers, made from brass or aluminum teeth clamped onto tape, deliver the most durability for denim, leather, and workwear but corrode outdoors and add significant weight. Available in finishes such as brass, nickel, and gunmetal, metal zippers are often chosen specifically to elevate project appearance with a classic, polished look.

Match the zipper to the job, and you'll avoid premature failure.

How Zippers Changed the Way We Think About Clothing

Before zippers, getting dressed meant wrestling with buttons, hooks, and laces — a slow, often frustrating process that shaped how clothing was designed and who could afford to wear it well. Zippers changed that entirely. They made dressing faster, allowed tighter fits in pencil skirts and sheath dresses, and enabled mass-produced ready-to-wear fashion that brought stylish clothing to everyone.

But zippers didn't just solve a practical problem — they triggered a shift in fashion psychology. What started as functional symbolism on military uniforms and rubber boots became a bold design statement. By the 1960s and 1970s, exposed zippers on leather jackets signaled rebellion and identity. Designers like Schiaparelli treated them as art. You now wear a fastener that redefined how clothing communicates who you are. The 1937 "Battle of the Fly" marked a turning point when French designers praised zippers as superior to buttons, cementing their place in fashion history.

In recent years, the zipper has experienced a notable revival on the runway, with FW23 metallic zippers making a striking reappearance across multiple high-fashion collections as deliberate design statements rather than mere closures.
