Nomex pants made out of

• A. Nomex IIA Aramid 95 Nomex 5 Kevlar and 2 carbon fiber
• B. Nomex II A Aramid 95 Nomex 5 Kevlar and 2 carbon fiber
• C. Nomex IIA Aramid 95 Nomex 4 Kevlar and 2 carbon fiber
• D. Nomex IIIA Aramid 95 Nomex 5 Kevlar and 2 carbon fiber

Answer: (A)

Protective pants for firefighting use a carefully engineered fabric blend to balance flame resistance with strength and durability. Nomex IIA is a family of inherent flame‑resistant fabrics chosen for turnout gear because it maintains rigidity under heat while still being workable as clothing. In this blend, about 95% Nomex provides the flame resistance at the core. Adding 5% Kevlar boosts tear and abrasion resistance, helping the fabric stand up to rubbing, snagging, and long wear. The remaining 2% carbon fiber adds dimensional stability and extra resistance to heat creep, helping the fabric hold its shape under stress. Together, these components give pants that resist direct flame exposure, keep their integrity during hard use, and remain flexible enough to wear comfortably. Other options switch the Nomex grade or fiber proportions, which changes the protective performance and is not the same material profile used for these pants.
