Ariat denim fit & size guide

Men’s M fits

The M number describes a fit family. Check each style for its rise and leg shape.
Fit	Seat & thigh	Leg shape
M1	Vintage, closer fit	Straight
M2	Traditional, roomy fit	Tapered bootcut
M3	Loose, extra room	Straight
M4	Relaxed, extra room	Bootcut or straight
M5	Straight, less room than relaxed	Straight
M7	Slim, close fit	Straight
M8	Modern, slim fit	Narrow opening

M4 does not mean one identical cut. Bootcut widens toward the hem; straight leg stays more even below the knee. Workwear versions can also differ in rise and construction.

Choosing your size

Measure your waist, fullest hip and inside leg. In a size such as 32 × 34, the first number is waist and the second is inseam, in inches. Try the length with the boots or shoes you plan to wear.

Regular, Rebar and FR are separate shopping groups. FR means flame-resistant; Rebar alone does not indicate an FR rating. Check the selected garment’s stated rating for your workplace requirements.
