Portwest FR33 T-Shirt: Bizflame™ Knit Engineering, High-Impact ARC2 Protection (15 cal/cm²), and Ergonomic Architecture

The FR33 is a high-performance base or outer layer garment, designed to provide superior technical protection in complex industrial environments. Made with Bizflame™ Knit fabric, this t-shirt inherently integrates flame resistance and antistatic properties necessary for environments with explosion risk (ATEX). Its ergonomic architecture, with raglan sleeves and reinforced seams with aramid thread, ensures the operator maintains complete freedom of movement while enjoying a world-class safety barrier.

Critical Operational Capabilities

• Advanced Electrical ARC Protection: Certified under international standards (NFPA 70E and IEC 61482-2), it offers critical resistance to electric arcs with an ATPV value of 15 cal/cm² and an ELIM of 13 cal/cm². This technical capability is fundamental for safety protocols in electrical maintenance and high-risk operations.
• Multi-Hazard System and Thermal Comfort: Provides certified defense against contact, convective, and radiant heat (NFPA 2112). The lightness of the Bizflame™ fabric ensures efficient thermal regulation, allowing the garment to be used for full shifts under demanding conditions without compromising worker well-being.
• Tactical Functionality and Integration: Incorporates two secure access hidden pockets (chest and sleeve) with specific compartments for writing tools, optimizing carrying capacity without altering the garment's technical aesthetic. Additionally, its UPF 40+ protection blocks 98% of UV rays, extending its operability to outdoor work environments with intense sun exposure.
