Men's wholesale workwear — work shirts, pants, FR clothing and hi-vis safety apparel.
Workwear is clothing bought to a specification: work shirts and pants that survive industrial laundering, flame-resistant garments rated for arc and flash-fire hazards, and high-visibility apparel built to ANSI classes for road and construction crews. The manufacturers below supply that trade - uniform rental and direct-purchase programs, safety distributors and workwear retailers. Hi-vis and FR are folded into this directory because the same buyers purchase them with the core work clothing, usually from the same programs.

Core workwear - shirts, pants, shorts, coveralls and outerwear in durable twills - sells through uniform programs and workwear retailers, and is judged on cost per wear: fabric weight, seam construction and laundering survival. The manufacturers in the listings are the names behind those programs, some selling work clothing for a century.
Flame-resistant clothing is a regulated specialty: garments are rated to standards such as NFPA 2112 for flash fire and arc ratings for electrical work, and employers buy them under written hazard assessments. High-visibility apparel is the third business, specified by ANSI/ISEA 107 class - Class 2 and Class 3 vests, shirts, sweatshirts and rainwear with reflective tape placement set by the standard. FR and hi-vis overlap constantly, and combined garments exist for crews who need both.
Program buyers should fix the specification first - fabric, color, FR or hi-vis rating, logo placement - then hold suppliers to continuity, because a workforce in mismatched garments is a program failing in public. Ask about size range including tall and extended sizes; workwear that stops at XL excludes part of almost every crew.
Retail buyers stock the brands their local industries wear, leaning on the distributor network the manufacturers sell through. Either way, the quality signals are unglamorous and consistent: bartacked stress points, heavy zippers, fabric that keeps its color and, for hi-vis, tape that stays reflective after repeated washing. The listings are the manufacturers whose garments are built to that test.
FR means flame-resistant: the fabric is engineered to self-extinguish and to limit burn injury in flash-fire or arc-flash events, and garments are certified to standards such as NFPA 2112. FR clothing is specified by the employer's hazard assessment, not chosen by preference.
ANSI/ISEA 107 sets performance classes for high-visibility apparel. Class 2 garments suit workers near traffic up to 50 mph; Class 3 adds sleeves and more reflective material for the highest-risk road work. Many vests and shirts in the listings state their class.
Uniform rental and direct-purchase program operators, safety equipment distributors, industrial suppliers and workwear retailers. Individual employers usually buy through a program or distributor rather than directly from the manufacturer.
