A: The 11oz canvas used in the Ariat M4 Workhorse is tighter-woven and generally more abrasion-resistant than standard FR denim. For oilfield workers dealing with rough equipment and abrasive surfaces, this canvas construction resists tears and snags more effectively, extending the garment's lifespan in harsh conditions.
A: Yes, the Ariat M4 Workhorse pants feature a flat hammer loop and a dedicated multi-tool pocket designed to support the weight of pliers, testers, or hammers without sagging. The reinforced construction ensures these high-stress areas hold up to the daily demands of electrical work.
A: Yes, the Boot Cut design of the M4 Workhorse is specifically engineered with a wider leg opening to accommodate bulky footwear, including logger-style climbing boots and wedge-sole safety boots, ensuring the pant leg stays down to protect the ankle and boot shaft.
A: These pants are CAT 2 rated and meet both NFPA 2112 (for flash fire) and NFPA 70E (for arc flash) standards. This dual compliance makes them suitable for most refinery and petrochemical sites requiring daily wear FR clothing.
A: The No-Rub Comfort Inseam removes the bulky, protruding seam often found in heavy work pants. For professionals walking long distances or constantly crouching, this flat-seam construction prevents chafing and irritation along the inner thigh, significantly improving all-day comfort.
