Product Description
CAT 2 / HRC 2, 20.0 cal/cm² ATPV flame-resistant straight leg jean — NFPA 70E and NFPA 2112 compliant
The Ariat FR M3 Straight Leg Jean is a men's flame-resistant work jean rated CAT 2 / HRC 2 with a 20 cal/cm² ATPV for dual-hazard protection against flash fire and electrical arc. It meets NFPA 70E and ASTM F1506 performance requirements and is UL classified to NFPA 2112, making it built for high-risk environments where electricians, oil and gas crews, and welders need reliable arc flash and flash fire protection. The loose fit adds extra room through the seat and thigh for bending and climbing, while the stackable 18" straight leg tapers cleanly over boots — all in rugged 13 oz ring-spun cotton denim.

Fit FAQ
- What size should I order in the FR M3 Loose?
- Order your true body-waist measurement. The FR M3 Loose is sold by waist in inches, so if your waist measures 34 inches, order a 34. The FR M3 is a low-rise jean; the waistband sits about 2 inches below your natural waist.
- Does the FR M3 Loose run true to size?
- Yes. The FR M3 Loose is cut loose through the seat and thigh. 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 M3 Loose?
- 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 M3 Loose?
- 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.
