The wool version of the Aireator. Wooleator's are a non-padded, thin sock that stands up beautifully to 4-season use. They are an even better choice any time moisture is in the forecast or when riding in mountainous terrain. Wooleator's are a favorite among our ambassadors and an absolute must have by the entire DeFeet staff. Very thin, unbelievably durable, and made with the highest quality grown in USA wools, Wooleator is unique among all wool socks.
