FR Shirts for Men 6.5oz Button Down Cotton Flame Resistant - Relax Fit

Our review of this FR work shirt finds it best suited for industrial trades that need reliable, wash-stable flame protection without extra bulk. Built from 6.5oz 100% cotton twill and treated with a durable flame retardant finish, the shirt balances comfort and certified protection for welders, electricians, ironworkers, and other hands-on professionals. The single biggest reason to buy is the combination of UL classification to HRC2 standards and a prewashed, wrinkle-resistant relax fit that fits big and tall sizes without guessing on shrinkage.

Key Features

• Material and finish: Made from 6.5oz 100% cotton twill with a water-repellent finish to shed light moisture on job sites.
• Certified flame protection: UL classified with an Arc Rating Atpv of 8.2 cal/cm2 and compliant with NFPA2112, NFPA70E, and ASTM F1506 for flash fire and arc hazard protection.
• Durability in construction: Features FR buttons and FR sewing thread so protective elements are integrated rather than added on.
• Prewashed, preshrunk fit: Relax fit is prewashed and preshrunk to reduce post-wash surprises and provides room for movement.
• Long-lasting protection: Flame resistant properties are rated to remain effective through up to 100 washes under recommended care.
• Work-ready styling: Classic uniform button-down look with a left pocket that includes the FR and UL NFPA2112 tag for quick verification.

Who It's For

This shirt is aimed at professionals who need certified flame resistant apparel that still looks and feels like a standard work shirt. It is ideal for welders, fitters, electricians, ironworkers, and contractors who work around flash fire or arc hazards and prefer a cotton twill that is lighter weight and breathable.

Those who should look elsewhere include workers requiring higher arc ratings than HRC2 or garments with specialized layering systems; also users who want stretch synthetics or heavily insulated outerwear for cold-weather conditions should consider alternate options.
