We love wool - the perfect combination of insulation and ventilation. Soft wool provides excellent insulation in cold weather, has a cooling effect in the heat, and can be used year-round. Even when wet, wool retains its fantastic ability to keep you warm. Wool doesn't need to be washed as frequently and doesn't retain odors in the same way as synthetic fabrics. Often, simply airing it out is enough to make it as good as new.
