Premium Flame Resistant Protection

The Portwest PW3 Modaflame Knit Hi-Vis FR Full Zip Sweatshirt represents the perfect fusion of advanced safety technology and everyday comfort. Designed for professionals who face flame and heat hazards in their working environment, this sweatshirt delivers multi-norm protection without compromising on style or practicality.

Innovative Modaflame Knit Technology

At the core of this garment is Portwest's cutting-edge Modaflame Knit fabric, constructed from 60% Modacrylic, 39% Cotton, and 1% Carbon Fibre at 300gsm. This unique blend delivers inherent flame resistance that is permanently built into the fibre structure itself. Unlike chemically treated FR fabrics that can lose their protective qualities over time, Modaflame technology ensures your protection remains constant regardless of how many times the garment is washed or worn.

Enhanced Visibility and Arc Flash Protection

The high-visibility design meets EN ISO 20471 Class 1 standards, ensuring workers remain visible in low-light conditions and busy industrial environments. Combined with certified arc flash protection meeting IEC 61482-2 standards with an impressive ATPV rating, this sweatshirt provides comprehensive protection for electrical workers and those in environments where arc flash hazards exist.

Comfort-First Design

The high cotton content within the Modaflame Knit blend ensures exceptional comfort throughout extended wear. The soft-touch fabric feels comfortable against the skin whilst maintaining its protective integrity. Ribbed cuffs and hem provide a secure, draught-free fit that retains warmth without restricting movement.

The convenient full-length zip design allows for easy on and off, whilst providing versatile temperature regulation. Whether worn as a standalone mid-layer or beneath additional FR outerwear, this sweatshirt adapts to changing conditions and layering requirements throughout the working day.
