The Nomex® Essential Arc Cargo Work Pants – Style 3235PT7 provide premium flame-resistant and arc-rated protection for industrial workers operating in high-risk environments. Made with a durable 6.5 oz Nomex® Essential Arc fabric blend of 65% modacrylic / 33% Nomex® & Kevlar® / 2% antistatic fibers, these pants deliver inherent FR performance that will not wash out.

The pants feature practical cargo functionality, including front slash pockets, dual multi-use cargo pockets with concealed buttons, and back welt pockets with flaps for secure storage. Built with high-resistance Nomex® thread, bar-tacked stress points, and a YKK brass FR zipper, they offer long-lasting durability and structural integrity.

For visibility and worksite compliance, the pants incorporate 3M™ Scotchlite™ FR reflective striping (¾" silver on 2" lime-yellow FireWeave), placed horizontally around each leg for enhanced night and low-light visibility. Classified as PPE Category 2 with an ATPV of 9.4 cal/cm², they meet top industry safety standards, including NFPA 70E, CSA Z462, and ASTM F1506.
