Product Description

The Ariat FR M4 Relaxed Stretch DuraLight Boundary Boot Cut Jean carries a CAT 2, 14 cal/cm² arc rating, meets NFPA 70E and ASTM F1506, and is UL classified to NFPA 2112, so one pair covers arc flash and flash fire. It's made for electricians, linemen, oilfield crews and utility hands working in the heat: 11 oz DuraLight denim in a 69% cotton, 30% modacrylic, 1% spandex blend that dries quick and breathes, with DuraStretch to move when you climb and kneel. The M4 runs relaxed through the waist, hip and thigh and finishes in a 19 inch boot cut that goes over a work boot.

Fit FAQ
- What size should I order in the FR M4 Relaxed?
- Order your true body-waist measurement. The FR M4 Relaxed is sold by waist in inches, so if your waist measures 34 inches, order a 34. The FR M4 is a low-rise jean; the waistband sits about 2 inches below your natural waist.
- Does the FR M4 Relaxed run true to size?
- Yes. The FR M4 Relaxed is cut relaxed and roomy 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 M4 Relaxed?
- 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 M4 Relaxed?
- 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.
