Cold weather doesn’t just make work uncomfortable – it slows you down, drains energy, and impacts concentration. The Portwest Ultrasonic Heated Tunnel Gilet (S549) is designed to tackle that problem head-on, delivering intelligent warmth, weather protection, and all-day comfort in one practical layer.

At the heart of the gilet is its integrated carbon fibre heating system, providing targeted warmth to the core of the body where it matters most. With three adjustable heat settings, users can control their temperature depending on conditions and workload – whether working outdoors in winter, on exposed sites, or in cold industrial environments.

The ultrasonic heat-sealed baffle construction isn’t just about looks. It improves insulation, reduces cold spots, and enhances weather resistance, helping keep wind and moisture out while retaining warmth inside. Combined with water-resistant fabric and a durable outer shell, this gilet is built for real working conditions, not just occasional cold spells.

Powered by a rechargeable battery, the heating system delivers long-lasting warmth throughout the working day, making it ideal for outdoor workers, site teams, logistics staff, drivers, warehouse teams, and anyone exposed to cold environments for long periods.

Unlike bulky winter layers, the S549 is designed to be lightweight and wearable, making it perfect as a mid-layer under jackets or as a standalone outer layer in milder conditions. The sleeveless design keeps arms free for movement, tools, and tasks, while still protecting the core – the key to staying warm and productive.

This isn’t just about comfort. Staying warm improves focus, reduces fatigue, and helps people work better for longer. The Portwest Ultrasonic Heated Tunnel Gilet offers a practical, modern solution to one of the oldest workplace problems: working in the cold.

It’s not just warmth. It’s performance, protection, and productivity – powered by smart design and smart technology.
