Battery-powered warmth meets high-visibility safety in extreme cold

The Portwest S548 Hi-Vis Ultrasonic Heated Tunnel Jacket tackles brutal weather head-on with carbon fibre heated panels and advanced ultrasonic baffle construction. Three heat settings at your fingertips mean you control the warmth whilst staying visible and protected on site. Whether you're working utilities in January or managing a construction site through winter months, this jacket combines serious insulation with battery-powered heating technology that actually works.

Key Features:

• Carbon Fibre Heated Panels: Battery-powered heating panels embedded throughout the jacket deliver customisable warmth via three heat settings, controlled by a simple chest button. The rechargeable battery pack includes a micro USB charging cable and loads easily into the jacket.
  
• Ultrasonic Baffle Construction: Heat-sealed ultrasonic baffles increase water resistance whilst maintaining breathability and windproofing. Heat-sealed seams throughout provide additional protection against water and wind penetration, keeping you dry in wet conditions.
  
• EN ISO 20471 Class 2/3 Certified: Certified to Class 2 in size S and Class 3 in size M upwards, with heat-applied segmented reflective tape for maximum visibility. The certification remains valid after 25 washes, and the 40+ UPF rated fabric blocks 98% of harmful UV rays.
  
• Premium Insulation System: Fully lined with Insulatex™ lining that traps heat quickly, combined with heavy-duty 260g polyester padding throughout. The 100% polyester taffeta lining adds durability whilst the insulation keeps the cold out even before you switch on the heating.
  
• Water-Repellent Outer Shell: 100% polyester pongee ripstop with TPU membrane, finished with PFAS-free Texpel™ Splash Eco coating that causes water to bead away from the surface. Built tough for demanding outdoor work.
  
• Practical Design Features: Detachable hood, two side zip pockets plus internal pockets for secure storage, elasticated cuffs, drawcord adjustable hem, and easy-grip pullers on all zippers for gloved operation. The chin guard with internal storm flap adds extra comfort and weather protection.
