Portwest Bizweld Work FR 11.2 Cal Arc Rated CAT 2 Cargo Pants

The Portwest Bizweld Work FR 11.2 Cal Arc Rated CAT 2 Cargo Pants are engineered for use in environments where flame and electric arc hazards may be present.

With an ATPV of 11.2 cal/cm², these pants meet PPE Category 2 arc flash requirements while maintaining breathable, all-day wearability. The fabric is designed to retain its flame-resistant properties for the life of the garment. An elasticated back waistband supports a secure fit, and multiple storage pockets allow for practical jobsite functionality.
