Wool: The Ultimate Winter Fabric

Baby, it’s cold outside! When you want to be swaddled in warmth, wool is your best choice. Unlike some synthetic yarns, wool does not conduct heat easily; this means that it traps body heat, helping to keep you warm. That’s why wool doesn’t have to be bulky; even a thin wool layer can keep you warmer than a thick sweater made of a more porous fiber.

Heat-of-sorption tableEven when it gets wet, wool maintains its ability to keep you warm. Merino wool can absorb up to 35% of its weight in water without feeling clammy. When it is cold outside, wool actually generates heat through a process known as “heat of sorption”: as the fabric absorbs moisture from the air, it releases stored molecular energy as heat!

Finally, wool is naturally anti-microbial and odor-resistant. Unlike polyester fleece fabrics, wool scarves and wraps can be worn many times without retaining any scent. Wool throws can cover your feet on the sofa for weeks without starting to smell like old socks.
