The high quality wool regulates heat in hot or cold weather and is incredibly soft. The wicking ability really makes this an amazing beanie, meaning a hat that feels soft and stays dry, both inside and out, under nearly any conditions.

Wool is the best beanie material because it naturally absorbs and releases up to 30 percent of its weight in moisture, which can keep you warm or cool, depending on the weather. Ribbing's important, too, as it gives the hat shape and helps it last longer.

Some people wear beanies for sun protection, especially if they have thinning hair. Beanies also add style while covering bald spots. A wool beanie can keep your head warm in the winter. A cotton beanie can absorb sweat and keep you cool in the summer months.
