Which statement describes a purpose of the moisture barrier?

• A. Insulation and thermal protection
• B. Color coding the garment
• C. Bacterial barrier only
• D. Improves breathability

Answer: (A)

The moisture barrier is meant to keep moisture away from the skin and from soaking the insulating layers, which preserves the insulation’s ability to trap heat. When the insulation stays dry, its insulating value remains high, preventing heat from flowing out and giving better thermal protection in wet or hot conditions. Color coding the garment isn’t related to the barrier’s function, and while a barrier can offer some liquid protection, it isn’t primarily a bacterial barrier. Breathability is typically not improved by a moisture barrier; it can even reduce vapor transfer, though some designs try to balance moisture blocking with some breathability. The main purpose is to maintain insulation and thermal protection by preventing moisture from reaching the skin and saturating the lining.
