Beat the cold with the FREDD MARSHALL USB Heated Vest — an electrically warmed layer engineered for sub-zero comfort. Powered by any standard 5V USB power bank, its multi-zone carbon-fiber heating elements deliver fast, even warmth across the core and back, while the lightweight polyester shell keeps the silhouette trim enough to wear under a jacket or on its own. Adjustable heat settings let you dial in exactly the warmth you need for the conditions.
