Which fiber is commonly used in making outdoor clothing and activewear because of its moisture-wicking capabilities and warmth when damp?

• A. Polyester
• B. Merino Wool
• C. Nylon
• D. Acrylic

Answer: (B)

Moisture management and staying warm when damp rely on fibers that move moisture away from the skin while still providing insulation. Merino wool does this particularly well because its fine fibers trap pockets of air, giving natural insulation. It can absorb a fair amount of moisture without feeling wet, so you stay warm even if you’re sweating or exposed to damp conditions. At the same time, it wicks sweat from the skin to the outer surface where it can evaporate, helping regulate temperature during outdoor activity. Synthetics like polyester and nylon can wick moisture and dry quickly, but they don’t insulate as well when damp. Acrylic can feel warm when dry but tends to trap moisture and isn’t as breathable or comfortable in damp conditions.
