Fit FAQ
- What size should I order in the FR M5 Straight?
- Order your true body-waist measurement. The FR M5 Straight is sold by waist in inches, so if your waist measures 34 inches, order a 34. The FR M5 is a mid-rise jean; the waistband sits just below your natural waist.
- Does the FR M5 Straight run true to size?
- Yes. The FR M5 Straight is cut slim through the seat and thigh with a straight leg. Order your normal jean waist; if you are between waist sizes, size up one inch for all-day comfort.
- What inseam should I choose in the FR M5 Straight?
- Ariat men's jeans are offered in 30, 32, 34 and 36 inch inseams. Pick the inseam closest to your true inside-leg length; a stackable straight leg allows about 1 inch of stacking over a boot.
- What is the arc rating of the FR M5 Straight?
- Flame-resistant garments carry an Arc Thermal Performance Value (ATPV), measured in cal/cm2. The exact rating depends on the fabric weight of the specific style — check the garment label or the product's FR ATPV rating before relying on it for an arc-flash hazard assessment.
