The Portwest FR737 PW3 Modaflame Knit HVO Class 1 FR Sweatshirt is for workers exposed to heat in their working environment. It protects against radiant, convective and contact heat, adds high visibility, and is anti-static for work in ATEX environments.
The flame resistance is inherent to the fibres, so it stays with the garment through washing. A crew neck with ribbed collar, cuffs and hem makes it easy to wear on long shifts, and the fabric holds its colour and size well over time.
