Which items make up the three layers of bunker gear?

• A. Outer shell, Moisture Barrier, Thermal Layer
• B. Outer shell only
• C. Moisture Barrier only
• D. Thermal Layer only

Answer: (A)

Bunker gear is designed as a three-layer system to provide outer protection, moisture control, and insulation. The outer shell is the rugged exterior fabric that takes the abuse from environment, abrasion, and contact with surfaces. The moisture barrier sits between the shell and the inner lining to block water and vapor from soaking into the insulation, helping keep the wearer dry while still allowing some vapor to escape. The inner layer, the thermal liner, provides insulation to slow heat transfer and protect the firefighter from radiant and conductive heat.

All three layers work together as a complete protective system, meeting standards for safety and performance. Choices that mention only one layer don’t offer the full protective setup.
