Keeps you warm in winter and cool in summer.Regulates body temperature by ensuring the body gets to a comfortable sleeping temperature more quickly and stay there for longer.Breathes more naturally than down and synthetic products.Quickly wicks away moisture without making you feel cold or clammy. Less time is spent tossing and turning.Wool acts like a thermos; even the sheep do not get cold on a bitterly freezing, snowy day, nor on hot sweltering summer’s day in a pasture. Their wondrously created wool fibers insulate the sheep just as myComforter insulates us. Sleeping cooler in the summer and warmer in the winter is the dream-come-true.Lasts for many years with proper care.
