Fabric Composition
Inherent Fabric: 65% Modacrylic, 33% Meta-Aramid & Para-Aramid and 2% Antistatic fiber
Inherent arc thermal performance value is due to its molecular structure. The fiber will not burn inherently. Its flame resistance comes from the fiber itself instead of the chemicals on the surface. Thus, the flame resistant performance is permanent and will not be washed out or worn away.

Comfort
In a survey, compared with common flame resistant cotton, Nylon blended fabric and aramid fabric with the same grammage, ArcPro is more comfortable. It performs much better in the feelings of stabbing, weight, flexibility, stiffness, close-fitting, stuffiness and itchiness.

Durability
With much longer life, its inherent permanent protection will not degrade through wash or wear. And the fastness is twice that of common flame resistant cotton and Nylon blended fabric
