Ariat Pants Explained: What's the Difference Between M1, M2, M4, M5, M7 & M8?

When it comes to workwear that combines durability with comfort and style, Ariat jeans and pants have carved a serious niche. But if you've ever shopped for Ariat denim, you’ve likely stumbled across the confusing letter-number combinations like M1, M2, M4, M5, M7, and M8.

What do these codes actually mean? More importantly, which one is right for you?

Let’s break it down.

What Do the “M” Numbers Mean in Ariat Pants?

The “M” stands for Men’s fit, and the number (1, 2, 4, 5, 7, or 8) refers to a specific cut, fit, and style. Each is designed to suit different body types, personal preferences, and types of work or wear.

Here’s a clear breakdown of each:

M1: Classic Fit

Fit: Slim through seat and thigh
Leg: Straight
Rise: Mid-rise
Best for: A traditional look with a close, clean cut.

M1 is Ariat’s most classic, tailored fit. It’s a solid choice if you like your jeans to fit snug without being tight and prefer a more polished silhouette.

M2: Relaxed Fit

Fit: Relaxed through seat and thigh
Leg: Bootcut
Rise: Mid-rise
Best for: Maximum comfort and range of motion.

Compared to the M1, the M2 gives you a bit more room where it counts. Great for workdays on the move or if you like a bit of extra space without sacrificing structure.

M4: Low Rise, Relaxed Fit

Fit: Relaxed through seat and thigh
Leg: Bootcut
Rise: Low-rise
Best for: Those who like a modern look with room to move.

The M4 combines the comfort of a relaxed fit with a low-rise waist, making it a favorite for those who want style and functionality. It pairs well with untucked shirts and a casual vibe.

M5: Slim Fit, Bootcut

Fit: Slim through seat and thigh
Leg: Bootcut
Rise: Low-rise
Best for: A trend-forward look with workwear durability.

If you like a sleeker silhouette but still need work-ready performance, the M5 is your go-to. It’s slightly more fitted than the M2 or M4, making it great for everyday wear or dressing up denim.

M7: Slim Fit, Straight Leg

Fit: Slim through seat and thigh
Leg: Straight
Rise: Mid-rise
Best for: Clean, modern lines without extra fabric.

The M7 keeps it sleek and straight. This fit is ideal for guys who want a stylish, minimal look that works as well in the city as it does on the ranch.

M8: Slim Taper Fit

Fit: Slim through seat and thigh
Leg: Tapered
Rise: Low-rise
Best for: A fashion-forward fit with a modern edge.

The M8 is the slimmest Ariat pant you’ll find. It tapers at the ankle for a more streetwear-inspired silhouette. Perfect for those who prefer a slim, modern jean that still works hard.
