The RaceQuip 110 series single-layer pant is 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 treatment is absorbed into the cotton fibers, with proper care; the garment will retain its flame retardant properties beyond the useful life of the garment.All pants are assembled with heavy-duty, multi-needle, over-lock safety stitch machines to provide exceptional seam strength. All pants feature a high quality, heavy-duty two-way YKK zipper built on FR tape installed with a double overlap for a more secure front opening. Stylish contrasting full-length leg stripes. Add to this the deep bag pockets and you have a single layer pant that provides an outstanding value.
