Workrite uniforms provide superior protection in lightweight fabrics, flame resistant properties that come from the chemical basis of the fiber itself. No treatments or chemicals are added to the fiber or fabric of these Workrite uniforms so as long as your garment is intact, your protection is with you. Made from a blend of Nomex, Kevlar and a permanently anti-static fiber, Workrite uniforms are extremely durable and can be expected to last at least three to five years. This means you spend less time, energy and money on replacements. And because the fiber is so durable, fabrics of Nomex are manufactured in lighter weights than everyday fabrics, adding even more comfort to your Workrite uniforms.
