Ariat Work FR Men's M4 Flint Boot Cut Flame Resistant Jean

The Ariat Work FR M4 Flint Jean combines the classic look of Western denim with the rigorous safety standards required for hazardous industrial environments. Constructed from durable 13 oz. ring-spun FR cotton, these jeans offer a relaxed fit through the waist, hip, and thigh, ensuring maximum mobility for climbing, kneeling, or operating heavy machinery. With dual-hazard certification (NFPA 2112 and NFPA 70E) and an ATPV rating of 20 cal/cm², the M4 Flint provides reliable CAT 2 protection without sacrificing the comfort needed for long shifts.

Key Features

Fabric Material 13 oz. 100% Ring-Spun FR Cotton Denim
Seam Construction No-rub comfort inseams to prevent chafing
Pocket Configuration Extra-deep front pockets with specific I-pocket for technology

Boot-Ready Design The boot cut leg opening easily stacks over logger, wedge, or square-toe work boots.
Enhanced Durability Ring-spun denim and reinforced belt loops withstand the abrasion of rough job sites.
Ergonomic Comfort Low-rise waist and relaxed fit prevent binding when bending or crouching.

Usage & Fit

  • Fit Guide: The M4 is Ariat's most popular work fit. It features a low rise and is relaxed through the seat and thigh, offering more room than the M5 slim fit but less bulk than traditional loose fits.
  • Sizing Note: 100% cotton denim may experience slight shrinkage; follow care instructions carefully. Order your standard jean size.

Ideal For

  • Oil & Gas Workers: Provides necessary flash fire protection while fitting comfortably over mud boots.
  • Electricians & Linemen: High ATPV of 20 cal/cm² offers substantial arc flash protection for energized work.
  • Welders: Heavy 13 oz denim resists sparks and slag better than lighter weight FR blends.

Frequently Asked Questions

Q: What’s the difference between Ariat “Flint” and “Shale” in the M4 FR jeans?

A: “Flint” and “Shale” are two different denim washes. In Ariat’s FR line, Shale is the darker wash, while Flint is typically slightly lighter. The main difference is the shade of the denim, not the overall purpose of the jean.

Q: Which wash hides dirt and wear better — Flint or Shale?

A: If you’re choosing based on day-to-day appearance, darker washes like Shale generally hide grime and scuffs better. Flint has more visible contrast and may show dust or stains sooner.

Q: How does the M4 Relaxed Fit compare to slimmer work jean fits?

A: The M4 is designed to be relaxed through the waist, hip, and thigh, which helps reduce binding when bending, crouching, or working in and out of equipment. If you prefer a trimmer fit, Ariat’s M5 is typically the slimmer option.

Q: Will the M4 boot cut leg opening fit over work boots?

A: Yes. The boot cut leg opening is designed to stack over common work boot profiles (including bulkier toe shapes). If you prefer an even slimmer leg opening, consider a straight or slim-straight model instead.

Q: Does this jean meet CAT 2 / HRC 2 requirements?

A: This jean is listed with an ATPV rating of 20 cal/cm² and a CAT 2 classification in the product specifications. Always follow your company’s safety program to confirm the right protection level for your jobsite.

Q: Are the belt loops durable enough for heavy tool belts?

A: Yes. This style features anchored and reinforced belt loops designed to hold up better under the weight of heavier tool belts and pouches during regular work use.

    Ariat FR jeans

    Posted by joe bailey on Nov 29th 2016

    I needed my FR jeans quickly, I was called up for a job on short notice. I ordered jeans and the jeans I received were different than the ones I ordered. They're the same brand, but the ones I chose online. I also was not too surprised as this was the second time this had happened. I have to have the FR clothes so I have no choice but to accept the order. FR depot was my favorite place to buy FR clothes but I'm going to look around for a new place to order from.
