Our Rationale

Why We Use Nomex® in Our Products

Permanent Protection

FR performance is inherent to the fiber — 50+ wash cycles without degradation. No re-treatment required, no performance fade, no compliance uncertainty.

Lightweight Comfort

210 gsm option provides all-day wearing comfort in hot environments without sacrificing protection. Suitable for shift workers in oil & gas and utilities.

Globally Certified

Used in products certified to EN 469, EN ISO 11612, NFPA 2112 and IEC 61482-2 — accepted by safety programs and EPC contractors worldwide.
