Which material provides warmth even when wet?

Which material provides warmth even when wet?

• A. Wool
• B. Cotton
• C. Nylon
• D. Polyester

Answer: (A)

When warmth must be maintained in wet conditions, the key is choosing fibers that keep insulating air even when damp. Wool does this best because its natural crimp and fiber structure trap many tiny air pockets, which provide insulation. It can absorb a fair amount of moisture without losing its loft, so you still stay relatively warm even if it gets wet. Cotton, in contrast, soaks up water quickly and loses insulation, making you heavy and cold. Nylon and polyester are quick-drying synthetics, but when they’re wet they don’t insulate as well as wool and can feel chilly.
