What Is a Coverall Zipper?

A coverall zipper is typically a long, closed-end zipper designed for full- or partial-body garments that require reliable, smooth function during frequent use. These zippers can be installed in the front, back, or side of the garment depending on your design, and they may feature one or two sliders based on access needs.

Coverall zippers are common in:

Protective workwear: Industrial coveralls, safety suits, and utility uniforms
Outdoor gear: Cold-weather or insulated coveralls for farming, fishing, and snow work
Specialty applications: Cleanroom garments, hazmat suits, and protective apparel

Whether you choose lightweight coil for flexible movement or rugged molded/metal chain for heavy-duty use, our coverall zippers are precision-built for the demands of your industry.

Other Zipper Styles:

Open End

Typically used on the front of jackets, can also be used on any items that require the zipper halves to fully detach from each other.

Closed End

Use for pants, sleeves on leather jackets, purses, tents or any application where a single slider, one-way closed end zipper is needed.

Tu-Way Open End

This zipper style has two sliders and can be opened from the top and/or bottom. Great type of zipper for heavy winter coats where more leg room may be needed for driving the car, while still keeping the top slider zipped up.

Coverall

As the name implies, this zipper is used on coveralls (overalls). One end is open and one end is closed. This zipper may be used on the legs of coveralls or used as the front zipper in coveralls.

Bag Style

This zipper works well for bags or any application that would benefit from a zipper that is closed at each end but allows for quick access by having two sliders. When the zipper is closed, the sliders meet in the middle (or any point on the zipper).

Bridge Top

This style of zipper is typically used on pockets or inside of purses. Both ends of the zipper are closed and the zipper has one slider.

Chain Material Options for Coverall Zippers

The chain type you choose directly affects how your coverall zipper performs in comfort, durability, and functionality. At Lenzip, we offer all major zipper chain materials for coverall applications: coil, molded plastic, and metal. Coil provides lightweight flexibility and smooth operation, making it ideal for garments where mobility is key. Molded plastic offers more structure and moisture resistance, perfect for outdoor or rugged environments. For the highest strength and abrasion resistance, metal chain is the go-to choice, delivering long-lasting performance for heavy-duty or premium workwear. Whatever your industry demands, we’ll match your coverall zipper with the right chain type to ensure consistent, dependable performance.

Slider Options

We offer a full selection of premium sliders for coverall zippers, precisely matched to your chain type, gauge, and intended application. Whether you need a single slider for straightforward closure or dual sliders for adjustable access and ventilation, we can help you configure the perfect setup for your garment. Each slider is chosen to balance smooth operation, durability, and user comfort—critical factors in workwear and protective apparel.

Our lineup includes Autolock for secure positioning, Long Pull for glove-friendly grip, Reverse Bail for compact designs, Nonlock for free movement, and other specialty configurations—available across all standard gauges and materials. These options ensure your coverall zipper performs flawlessly in any environment, from cleanrooms and safety gear to insulated suits for extreme weather.
