The RaceQuip 112 series single-layer driving pants are made from Pyrovatex FRC material. Pyrovatex offers the maximum combination of overall flame and heat protection, durability and comfort for the price. This FRC material retains the softness and breathability of cotton and will wick away moisture from the skin. Pyrovatex fabric is gentle and non-irritating to even the most sensitive skin. The treatment process leaves the exterior surface shiny and supple. Since the Pyrovatex 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. All driving pants are assembled with heavy-duty, multi-needle, over-lock safety stitch machines to provide exceptional seam strength. Stylish contrasting leg stripes match the full-length arm stripes on RaceQuip driving jackets. The black accents: leg and arm cuff and beltline give the driving pants a unique look and style. All this gives you single layer driving pants that provide an outstanding value. Exceeds SFI 3.2A/1 specs with a TPP rating of 11. Available in Black, Red and Blue with Black leg stripes and manufactured in sizes from Small – 4X-Large.
