Portwest S548 Hi Vis Ultrasonic Heated Tunel Jacket with Detachable Hood

Cutting-edge thermal technology and high-visibility safety are fused together in the Portwest S548, a heated tunnel jacket designed for the most extreme cold-weather conditions. The Portwest S548 features advanced carbon fiber heating panels powered by a battery pack, providing active warmth to the chest and back at the touch of a button. To ensure that heat is retained efficiently, the jacket utilizes an ultrasonic welded seam construction that eliminates traditional needle holes, preventing cold air from penetrating the insulation. This high-visibility garment is perfect for outdoor workers in freezing environments who need to remain seen and warm simultaneously. The detachable hood and adjustable hem allow for a customized fit and protection level depending on the weather, while the multiple zipped pockets offer secure storage for essentials. With its high-performance insulation and active heating capabilities, this jacket is a game-changer for those working in cold storage, winter construction, or emergency services.
