The RaceQuip 9162 series Chevron-5 multi-layer SFI-5 racecar driver's fire suit pants are made up of an outer layer of durable Nomex® and a soft, comfortable and lightweight Nomex® liner with Chevron pattern box quilting. A stretch waistband keeps the pants flexible but cinched for a custom fitted look. The Nomex® boot cuff legs are trimmed in black. The Chevron-5 pants feature a high quality, heavy duty Nomex® backed brass zipper installed with a double overlap for a more secure front opening. Internal bag pockets are included for convenience. Exceeds SFI 3.2A/5 specs. Available in Black in sizes Small - 3X-Large (refer to sizing chart). Note that sometimes these materials are referred to as "fireproof", but actually all auto racing safety gear is "fire retardant".
