Portwest Ultrasonic Heated Tunnel Jacket

Product Overview

The Portwest Ultrasonic Heated Tunnel Jacket is a sophisticated solution for professionals working in demanding, cold environments. By integrating modern heating technology with a specialised ultrasonic construction, this jacket provides active warmth without the bulk of traditional insulated coats. It is a well-engineered garment designed to maintain a professional appearance while offering superior protection against the elements.

Key Features

• Integrated carbon fibre heated panels provide adjustable warmth at the touch of a button, ensuring comfort during long shifts in low temperatures.
• Ultrasonic bonded seams create a wind-resistant barrier and prevent insulation from shifting, which eliminates cold spots common in traditionally stitched jackets.
• The lightweight polyester fabric allows for a full range of movement, making it ideal for active tasks where heavy outerwear would be restrictive.
• Elasticated cuffs and hem help to trap heat against the body, further improving the thermal efficiency of the garment.

Design & Performance

Crafted from 100% polyester, this jacket utilises a lightweight fabric that offers high performance without unnecessary weight. The ultrasonic 'tunnel' design is the standout feature; instead of using needles and thread which create thousands of tiny holes in the fabric, the layers are bonded together. This maintains the integrity of the outer shell and ensures maximum heat retention. The result is a sleek, modern aesthetic that performs exceptionally well in the field.

Customisation: Print Only

This item is available for PRINT customisation only. Due to the technical nature of the ultrasonic seams and the internal heating elements, embroidery is not a suitable method for this garment. Piercing the fabric with embroidery needles could compromise the thermal seals or damage the internal circuitry. Our in-house printing team ensures a crisp, durable finish for your logo that maintains the jacket's technical performance and professional look.

Use Cases

This jacket is an excellent choice for site managers, surveyors, and logistics professionals who transition between vehicles and outdoor environments. It is equally suited for warehouse staff working in cold storage or unheated facilities who require consistent warmth throughout the day.

Practical Advice

For the best results, we recommend wearing this jacket over a technical base layer or a medium-weight sweatshirt. This layering approach allows the heating elements to work effectively close to the body. Please refer to our size guide to ensure a correct fit, as a closer fit will improve the efficiency of the heated panels.

Caring for your product

To preserve the internal heating components and the specialised ultrasonic bonding, it is essential to follow the care instructions provided with the garment. Avoiding high-temperature washes is vital, as excessive heat can damage the technical fibres and the internal wiring.

Do not use bleach or harsh chemical cleaners, as these can degrade the polyester fabric and the printed customisation. When cleaning, ensure the garment is handled gently to maintain the integrity of the heat-sealed tunnels that keep the insulation in place.
