The Portwest S548 Hi-Vis Ultrasonic Heated Tunnel Jacket Orange is a high-performance insulated work jacket designed to provide superior visibility, warmth, and weather protection in demanding outdoor environments. Combining advanced heating technology with high-visibility safety standards, this jacket ensures workers stay warm, visible, and protected during cold conditions.
The jacket features battery-powered carbon fibre heated panels, delivering adjustable warmth directly to the wearer. Three heat settings can be easily controlled via a button on the chest, allowing the user to adapt the level of heat depending on working conditions. A micro USB charging cable is included with the durable battery pack for convenient charging.
Constructed from durable 100% polyester pongee ripstop fabric with a bonded TPU membrane, the S548 offers excellent wind resistance while remaining breathable and water resistant. Innovative heat-sealed baffle construction improves protection against wind and rain, while the PFAS-free Texpel™ Splash Eco finish causes water to bead off the fabric surface for enhanced weather protection.
Inside the jacket, the Insulatex™ thermal lining quickly traps body heat, ensuring reliable insulation even in harsh weather conditions. The padded tunnel design improves warmth retention while maintaining comfort and flexibility during active work.
Practical design features include elasticated cuffs, a drawcord adjustable hem, two secure side zip pockets, and internal storage pockets for personal items. These features make the jacket both functional and comfortable for long shifts outdoors.
