You’ll stay surprisingly warm in wool during winter since it can handle temperatures down to -20°F effectively. Wool’s secret weapon isn’t just trapping air like other fabrics – it actually creates heat through a chemical reaction when moisture from your skin contacts the fibers. This process, called heat of sorption, means wool generates warmth while you wear it.
The fiber’s natural crimp creates millions of tiny air pockets that act like personal insulation bubbles. Unlike cotton or synthetic materials, wool maintains its warming power even when damp, making it reliable in harsh conditions.
Different wool types offer varying warmth levels, with cashmere providing eight times more insulation than regular wool.
