A bold block-colour beanie from Coal that'll keep you comfy The Frena Beanie from Coal combines a bold block colourway in a fine acrylic construction to make an all-season beanie that'll keep you warm through the winter. The Coal Headwear legacy was built on this originator of the "modern fit". A heavy weight, fine-knit ribbed beanie that's often imitated but never duplicated. Featuring Coal's signature woven label, wear unrolled or cuffed, doubling your styling options.
