Fashioned after the first hat Kühl ever designed, the Alf Earflap Hat boasts a time-tested shape that's used widely in South America and is typically made from alpaca wool. The updated Alf Hat is made from wind-and-water-resistant microfleece fabric that dries quickly, wicks away moisture, and provides exceptional warmth. The hat's complex multi-piece pattern is oval not round, so it fits your head perfectly. Earflaps can be an essential tool in your arsenal against cold and wet elements, yet they flip up easily during less-threatening weather conditions. A chin strap secures the hat in chilly, windy weather and keeps the earflaps out of the way in warmer temperatures. Imported. One size fits most.
