The Race Quip 121 series multi-layer driving jacket is made up of an outer layer of durable Pyruvate FRC, backed by a layer of Nome, then lined by another layer of Pyruvate. Pyruvate offers the maximum combination of overall flame and heat protection, durability, match heavy-duty, and comfort This FRC material retains the softness and breathability of cotton and will wick away moisture from the skin. Pyruvate fabric is gentle and non-irritating to even the most sensitive skin. The treatment process leaves the exterior surface shiny and supple. Since the Pyruvate process combines a chemical agent with the raw cotton fibers to create a bond at the molecular level, with proper care; the garment will retain its flame retardant properties beyond the useful life of the garment.
