What is the hood composition?

• A. 3-ply composite fabric with nomex nano flex barrier quilted between jersey knit.
• B. 2-ply cotton fabric with vinyl coating.
• C. 4-ply polyester with silicone lining.
• D. 1-ply nylon with no barrier.

Answer: (A)

Hood protection relies on a layered, flame-resistant fabric design that blocks heat from reaching the head and neck while staying flexible and breathable. The 3-ply composite fabric with a Nomex nano flex barrier quilted between jersey knit provides that balance. The outer and inner jersey-knit layers give comfort and fit, while the Nomex nano flex barrier sits between them to resist heat transfer and flame exposure. Quilting the barrier in place keeps it from shifting, preserving protection without sacrificing mobility. This construction is aligned with how firefighting hoods are designed to meet heat protection standards. The other options fall short because they lack an effective heat barrier or use materials that aren’t reliably flame resistant. Cotton with vinyl can melt and emit fumes, a 4-ply polyester with a silicone lining may not deliver consistent thermal protection or durability, and 1-ply nylon with no barrier offers little to no protection from heat.
