The Patagonia Women's Beatrice Beanie is a warm beanie that features a 100% polyester fleece lining that wicks moisture, dries quickly, and stays soft and smooth against your skin. Outside, the 100% chlorine-free merino wool fibers have a dynamic pebbly texture and a supple feel; they shed moisture and resist wind and cold. The low-profile styling fits comfortably under a hood or helmet.
