Keep warm in bitter cold with these warm beanies. Each one is handmade with 100% wool (hand wash only, dry flat). The faux fur pom poms are removable if you need to take them off and can be fluffed up by using a hair dryer! The sizes are determined by head circumference. If you aren't sure what your head circumference, take a flexible tape measure (preferably one made for tailoring clothes) and wrap around your head from you forehead to the back and back to the starting point.
