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.
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.
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.
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.
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.
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.
Typical Ariat. I should have known not to order them online. No 2 pair fit the same! I have worn 34x36 for years, and I decided to get 35x36 just so it isn't so tight while wearing thermal underwear. I can barely get them over my ass! They are more like a 32x36. I should have known better but was desperate and needed them for work. Not going to help me now, shame on me I guess
Great fit. Very comfortable. Fits over my boots very well. Highly recommend.
The experience of ordering the jeans from you was good. Fast service and they were here.
Pants don't even look like work pants. They are very confertable and able to work well with them.
