What is the fabric composition of the yellow brush jacket and pants?

• A. Kevlar only
• B. Cotton blend
• C. Nomex IIA aramid fibers (93% Nomex, 5% Kevlar and 2% Carbon fiber)
• D. Polyester fabric

Answer: (C)

The protection comes from a flame-resistant aramid blend designed for wildland wear. The yellow brush jacket and pants use Nomex IIA aramid fibers, specifically 93% Nomex with 5% Kevlar and 2% carbon fiber. Nomex provides inherent flame resistance and heat protection, which is essential for brush work. The Kevlar adds strength and abrasion resistance so the fabric can withstand rough use without quickly wearing through. The small amount of carbon fiber helps with dimensional stability and heat performance, keeping the fabric from deforming under heat while keeping it light. The other fabrics don’t offer this combination of flame resistance, durability, and stability: cotton blends burn and degrade under heat, polyester can melt, and Kevlar alone doesn’t provide the same protective balance for outerwear.
