<p>A must-have outerwear for performance and style, this hybrid coat transforms from a sleek vest to a full-length coat. With its five precision-engineered heating panels, Helios delivers adjustable warmth exactly where you need it most. Two interior zip pockets feature built-in USB plugs that you can connect to any power bank (not included) to use the heating panels. The power bank must stay connected to the jacket and turned on during use. Remove the power bank when washing the jacket.</p>
