The RaceQuip multi-layer SFI-5 suit is made of an outer layer of durable Pyrovatex FRC, backed by a layer of Nomex, then lined by another layer of Pyrovatex. The middle layer consists of Nomex batting which is an inherently fire retardant aramid fabric. They are assembled with heavy-duty, multi-needle, over-lock safety stitch machines to provide exceptional seam strength. SFI-5 suit features a high quality, heavy duty Nomex backed brass zipper on FR tape installed with a double overlap for a more secure front opening. Stylish white armband stripes contrast the full-length black leg stripes. The black accents: high-back collar, leg and arm cuffs, epaulets and beltline, give RaceQuip driving suits a unique look and style. Add to this the pleated back panel for freedom of movement, boot cuffs, deep bag pockets and the adjustable euro-style belt, and you have a multi-layer racing suit that provides an outstanding value. SFI 3.2A/5 homologated.
