Pyrotect IB300520 SFI-Rated Fire-Retardant Nomex Innerwear Pants White X-Large

The Pyrotect IB300520 Sport Innerwear Bottom is an ultra-thin, SFI 3.2A/1-rated fire-retardant pant designed to be worn under any racing driving suit. Constructed from Nomex, these inner pants deliver a comfort-first experience while providing meaningful thermal protection — eliminating the scratchy, irritating feel often associated with traditional Nomex layers worn directly against the skin.

Key Features:

• SFI 3.2A/1 Certified — SFI label attached; meets sanctioning body requirements for fire-retardant underwear
• Nomex Construction — inherently flame-resistant material that will not melt or drip
• Ultra-Thin Design — fits comfortably under a driving suit without adding bulk
• Moisture Absorbing — highly absorbent fabric helps keep the driver cool and dry during competition
• Versatile Layering — can be worn under Nomex underwear for added Thermal Protective Performance (TPP), or under crew uniforms for supplemental fire protection
• Color: White
• Size: X-Large (Adult)
• Style: Long Pants / Bottoms only (top sold separately)

Fire-retardant underwear is one of the most cost-effective ways to increase a driver's protection against extreme heat and flame. The Pyrotect Sport Innerwear Bottom pairs with the matching top (sold separately) to create a complete base layer system that works with any SFI-rated or Nomex race suit.
