Portwest S557 Ultrasonic Heated Jacket with Zipped Pockets

Redefining winter workwear through technical innovation, the Portwest S557 offers active warmth for professionals who must operate in sub-zero temperatures. The Portwest S557 incorporates internal heating panels that provide targeted warmth to the core, significantly extending the amount of time a worker can stay productive in the cold. To maximize the effectiveness of this heat, the jacket uses an ultrasonic quilting technique that fuses the fabric without stitching, creating a superior windproof barrier that traps warm air inside. The lightweight design ensures that the jacket does not become bulky or restrictive, allowing for a full range of motion during manual labor. Secure zipped pockets on the Portwest S557 provide a safe place for tools and electronics, while the sleek profile makes it suitable for both professional and casual wear. This jacket is an essential investment for anyone in logistics, site management, or cold-chain operations who requires consistent thermal comfort without the weight of traditional heavy parkas.
