Ariat Men's Jean Fit Guide
Ariat's M-Series fit number describes how the jean fits through the waist, seat, thigh, rise, and leg. Use this guide to compare common Ariat work jean fits.
| Fit | Seat & Thigh | Rise / Waist | Leg | Best For |
|---|---|---|---|---|
| M3 Loose | Loose through the hips and thigh | Sits lower on the waist | Straight leg opening | Maximum room and freedom of movement |
| M4 Relaxed | Relaxed through the hip and thigh | Sits lower on the waist | Bootcut or straight leg, depending on style | All-day comfort with extra room to move |
| M5 Straight | Straight through the seat and thigh | Sits just below the waist | Slightly wider straight leg opening | Traditional straight fit without the extra room of M4 |
| M7 Slim | Slim through the seat and thigh | Sits below the waist; available in low and classic rises | Straight leg that fits over boots | Closer, more streamlined fit |
