Wrangler Riggs Workwear Men's 20X FR Vintage Boot Cut (Style 9S38)

Our review of the Wrangler Riggs Workwear Men's 20X FR Vintage Boot Cut Jean finds a purpose-driven work jean for tradespeople who need flame resistance without sacrificing a closer fit. These are slim fit jeans that still accept boots thanks to a bootcut leg, and the single biggest reason to buy is the built-in safety: a certified ATPV 21 CAL/CM2 rating and self-extinguishing fabric make them suitable for environments with thermal hazard concerns while remaining comfortable for long shifts.

Key Features

• Slim fit with bootcut: The jeans sit below the natural waist and are slim through the seat and thigh while the bootcut leg slips over work boots for practical on-site wear.
• Flame resistant construction: Designed to meet rigorous FR standards, the fabric self-extinguishes and carries an ATPV 21 CAL/CM2 rating for thermal hazard protection.
• Durable stretch blend: A stretch-cotton blend gives everyday durability with enough give for mobility during physically demanding tasks.
• Five-pocket storage: Classic 5-pocket styling provides two front pockets, a watch pocket and two back pockets for small tools and essentials.
• All-day comfort: Lightweight feel and stretch make these jeans comfortable in warmer climates and during extended wear on the job.

Who It's For

The Wrangler Riggs 20X FR boot cut jean is best for electricians, construction workers, welders, and other tradespeople who require certified flame resistant apparel but prefer a slimmer silhouette. It is also suitable for anyone who needs ATPV 21 CAL/CM2 protection while working outdoors or in industrial settings where thermal exposure is a concern.

Those who favor a looser, relaxed or carpenter cut should look elsewhere, as the fit runs slim through the seat and thigh and several customers reported sizing small. If you need heavy-duty denim built for extreme abrasion rather than FR protection, a heavier work jean may be a better option.
