Black Stallion Welding Pants Review: Built Specifically for the Arc, Not Adapted for It

Most FR pants started as work jeans. Someone added a flame-resistant treatment, certified them to NFPA 2112, and the welding market bought in because options were limited. Black Stallion went the other direction. The FD10 and F9 lines were engineered from the fabric selection outward for welding environments specifically - cuffless hem, aramid hardware, wash-durable FR protection. Here’s what that difference actually produces at the knee and the hem.

Black Stallion is the welding PPE line manufactured by Revco Industries, a welding safety company that also makes welding jackets, sleeves, and gloves. Their FR pants are distinct from general FR workwear in two ways: a cuffless hemline designed to fall over boot tops without gathering, and hardware (zipper tape, buttons) made from FR aramid and brass rather than standard components that can melt or transfer heat under flame exposure.

The direct verdict: Black Stallion FR pants are the right pick for welders who need pants designed around the actual hazards of arc work rather than adapted from general workwear. The FD10 stretch denim variant is the most wear-friendly option for mixed shop and positional work. The F9 FR cotton is the better choice for sustained overhead or heavy spatter environments where heavier fabric protection matters more than comfort.

The FD10 FR Stretch Denim: What It Is

The Black Stallion FD10 is a 10.5-ounce FR stretch denim made from 99% cotton and 1% spandex. The FR protection is rated through 100 home wash cycles, which is at the top of the range for FR denim at this weight. Most competitors rate their FR treatment at 50 washes.

The classic 5-pocket jean design with relaxed fit gives it an everyday-wear look, which matters for welders who drive to work in the same pants they weld in. The zipper tape is made from flame-resistant aramid fiber. The waistband button is brass, not plastic. These are the small details that separate a pant designed for welding from a pant designed for general industrial wear and approved for welding.

The F9 FR Cotton: Heavier Protection

The Black Stallion F9 is a 9-ounce flame-resistant treated cotton pant, available in green - a traditional welding industry color that marks the garment as dedicated PPE rather than everyday wear. The heavier, non-stretch cotton gives better protection margin against sustained heat and heavy spatter than the FD10 denim.

The F9 is rated through 50 home washes (or 25 commercial washes), which is lower than the FD10 but in line with standard FR cotton garments at this weight. For shops that rotate PPE on a regular schedule, the 50-wash rating is not a practical limitation - the pant will be replaced before it’s reached on most work schedules.

The Cuffless Hem: Why It Matters

This is the design feature that separates Black Stallion’s pants from the general FR workwear field. A standard hemmed cuff - even on good FR jeans like Carhartt’s - creates a fold of fabric at the boot top. Hot spatter falls into that fold. It sits there, transferring heat to the fabric and, if the exposure is long enough, initiating a char.

Black Stallion’s welding-specific pants are cut and hemmed to sit at the boot shaft without gathering. There is no cuff to trap spatter. The hem lies flat against the boot, and spatter that lands on the lower leg hits a flat surface and falls to the floor rather than sitting in a pocket of fabric.

For overhead stick welding, heavy plasma dross, or any work where significant spatter falls downward, this single design difference is the strongest argument for the Black Stallion over Carhartt or Wrangler FR.

Named Flaw: Sizing and Fit Inconsistency

Black Stallion FR pants have a more limited size run than Carhartt or Wrangler. The FD10 and F9 models are available in even-number waist sizes from 30 to 42 or 44 inches, with 30 and 32-inch inseam options. Welders who wear odd waist sizes, need 34-inch or longer inseams, or wear above a 44-inch waist will find the selection limited.

Fit also runs slightly narrow through the thigh on the FD10 compared to Carhartt’s relaxed fit. Welders who wear a true relaxed fit on Carhartt may need to size up on Black Stallion to get the same thigh room. The 1% spandex helps, but the overall cut is closer to a slim-relaxed than a traditional relaxed fit.

Black Stallion vs. Lapco FR: The Direct Comparison

Lapco FR is the other welding-specific FR pant brand you’ll encounter at this level. Lapco targets the oil and gas, pipeline, and utility sectors with heavy FR cotton and FR denim in both work pant and jean cuts.

Where Lapco FR has an edge: heavier fabric weights across the line, wider size runs (particularly in larger waist and longer inseam options), and widespread availability through industrial distributors. Lapco is more common on well sites and pipeline crews where heavyweight FR protection and industrial distributor supply chains matter.

Black Stallion’s edge: the welding-specific design details (cuffless hem, aramid zipper tape, welding-forward construction), the 100-wash FR rating on the FD10, and the direct Amazon availability for individual buyers who aren’t purchasing through an industrial account.

For a fabrication or structural welding shop, Black Stallion’s welding-specific design is the more targeted fit. For a pipeline or utility crew ordering through an industrial distributor, Lapco’s heavier coverage and distributor relationships often win.

FAQ

What makes Black Stallion pants specific to welding? The cuffless hem that fits over boot tops without gathering, FR aramid zipper tape, brass hardware, and FR protection rated through 100 home washes on the FD10 model. These details are absent from most general FR workwear brands that certify their pants for welding use without specifically designing for it.

Are Black Stallion FR pants made from FR cotton? The F9 model is 9-ounce flame-resistant treated cotton. The FD10 model is 10.5-ounce FR stretch denim (99% cotton, 1% spandex). Both are NFPA 2112 rated. The FD10’s denim construction gives better stretch and comfort; the F9’s heavier cotton gives better protection margin against sustained heat exposure.

How do Black Stallion pants compare to Lapco FR? Black Stallion’s welding-specific design details (cuffless hem, aramid hardware, 100-wash FR durability on FD10) give it the edge in a fabrication or structural welding environment. Lapco FR’s heavier fabric weights and industrial distributor availability make it more common in pipeline and utility sectors. For individual buyers on Amazon, Black Stallion’s direct availability is a practical advantage.

What is the FR certification on Black Stallion pants? Both the FD10 and F9 models are certified to NFPA 2112 for flash fire protection. The FR protection on FD10 is rated through 100 home washes; the F9 is rated through 50 home washes and 25 commercial washes.

Do Black Stallion pants run true to size? The FD10 runs slightly narrow through the thigh compared to a standard relaxed-fit jean. If you wear a relaxed fit in Carhartt or Wrangler, consider sizing up one waist size on Black Stallion to maintain comparable thigh room. The spandex helps with mobility but doesn’t fully compensate for the narrower cut.

Can Black Stallion pants be worn for non-welding work? Yes. The FD10 stretch denim looks like a regular dark-wash jean and works for general shop use, driving, and site work. The F9 green cotton is visually a PPE garment and is better suited to dedicated welding use rather than all-day wear. Both provide FR protection in any application where flash fire or arc flash hazard is present.

Where can I buy Black Stallion FR pants? The FD10 and F9 models are available directly on Amazon through welding supply sellers. They are also stocked at welding supply distributors (Airgas, Harris Industrial, CyberWeld) and through Revco’s authorized dealer network. Amazon is the most convenient source for individual buyers who need standard sizes.
