Hi-Vis Button-Down FR Shirt – CAT 2 & Class 3 Visibility

The Hi-Vis Button-Down FR Shirt (SLB4) represents the next generation of protective workwear—combining flame resistance, arc-flash protection, and Class 3 high-visibility compliance in a clean, professional button-down design.

Engineered for demanding job sites, this shirt delivers CAT 2 AR/FR protection and NFPA® 2112 compliance, while the color-blocked design enhances both safety and wearability. The hi-vis upper portion ensures maximum visibility in roadway and traffic environments, while the grey lower half helps conceal dirt, stains, and wear for a cleaner appearance throughout the day.

Designed for comfort, durability, and compliance, this FR shirt is ideal for crews working in utilities, construction, transportation, and industrial environments where arc flash, flash fire, and high-visibility protection are all required.
