coverall

Coverall, or coveralls in plural, refers to a one-piece garment designed to cover the torso and legs, and often the arms and back. It is worn as protective clothing in many industries to shield clothing and skin from dirt, stains, sparks, chemicals, or other hazards. Typical features include a front closure (zipper or buttons), elastic at the wrists and ankles, and sometimes an attached hood, knee patches, pockets, or reinforced seams.

Materials and variants vary widely. Reusable coveralls are made from fabrics such as cotton, cotton-polyester blends, denim, or other woven materials, sometimes with flame-resistant (FR) properties. Disposable coveralls are produced from nonwoven materials like polypropylene or SMS, and may be laminated for splash or chemical protection. Specialized versions provide flame resistance, chemical barriers, or waterproofing, using fabrics such as FR cotton blends, Nomex-based fabrics, or treated coatings.

Differences from related garments are primarily about coverage and construction. Coveralls are a single-piece outfit that fully covers the trunk and legs (and often the arms), whereas overalls are two-piece garments with separate pants and a bib, and jumpsuits are one-piece outfits that may differ in closure style or rear design.

Common uses span construction, painting, manufacturing, automotive and heavy industry, mining, and laboratory or cleanroom work. In hazardous environments, coveralls may be used with other personal protective equipment and must meet applicable safety standards, such as regional PPE requirements and fabric-specific certifications. Care and maintenance depend on material: reusable coveralls are laundered; disposable ones are discarded after use.
