For those cold winter days when your ball cap just won't cut it you need to have the great light Acrylic Beanie to keep the heat in. The Halla Beanie is made with 100% Acrylic. Its thin construction makes it light and comfortable for indoors and out. It has a double lining that makes it thick. The Beanie can also be un-cuffed/rolled down for those who like a little extra length.
