Portwest DX4 Insulated Work Jacket with InsulatexPro and Texpel Splash Eco

Built for Cold-Weather Work:

The Portwest DX468 is a heavy padded insulated work jacket designed for professionals working outdoors or on-site in cold conditions. Its InsulatexPro fill - 100% polyester at 240g - delivers serious warmth without adding unnecessary bulk, making it practical whether worn as a standalone outer layer or over a base layer on colder days.

Waterproof Shell and Eco-Conscious Finish:

The shell is built from Portwest Extreme Waterproof fabric: a 150D PU membrane polyester stretch rated to WP 20,000mm, so rain beads off the surface rather than soaking through. The PFAS-free Texpel Splash Eco finish achieves this water resistance without the use of per- and polyfluoroalkyl substances, making it a more environmentally responsible choice for the worksite.

Flotech Ventilation and 4-Way Stretch:

The Flotech System provides active ventilation and breathability, with the fabric rated at MVP 10,000g/m²/24hrs - important for anyone doing physical work where moisture build-up is a concern. The 4-way stretch construction and ergonomic raglan sleeves allow unrestricted movement across the full range of motion, so the jacket moves with you rather than against you.

Practical Features for Everyday Use:

Five pockets are included: zipped chest pockets, side zip pockets, and a dedicated phone pocket, so tools and essentials stay organised and accessible throughout the working day. A detachable hood adds flexibility depending on weather conditions.

Setup and Care

Getting Started:

No assembly required. Attach or detach the hood as needed before use. Check that all zips run freely prior to wearing.

Washing:

Machine wash at a maximum of 30°C using a mild process. Use a liquid detergent suitable for technical fabrics to maintain the Texpel Splash Eco finish.

Drying and Storage:

Drip line dry only. Do not tumble dry, iron, bleach, or dry clean. Once dry, store loosely folded or on a hanger in a dry location to retain the insulation loft.

Maintaining Water Resistance:

Over time, the Texpel Splash Eco finish can be refreshed by tumbling the clean, drip-dried jacket on a low-heat setting for a short period, or by applying a PFAS-free DWR reproofing spray after washing to restore water beading performance.

Frequently Asked Questions

Is this waterproof insulated jacket genuinely waterproof?

The shell is rated to WP 20,000mm, so rain beads off the surface rather than soaking through, even in sustained downpours. The Flotech System ventilation keeps moisture from building up inside, with breathability rated at MVP 10,000g/m²/24hrs. That combination makes it a practical choice for active outdoor site work where both weather protection and sweat management matter. EN 343 Class 4:1 certification independently verifies the rain protection.

Is the water-resistant finish on this jacket free from harmful chemicals?

Yes. The outer fabric uses a PFAS-free Texpel Splash Eco finish, which achieves water resistance without per- and polyfluoroalkyl substances. The jacket also holds Oeko-Tex Standard 100 accreditation, meaning it has been independently tested for harmful substances. For anyone working closely with food, children, or in sensitive environments, that independent verification is a meaningful assurance.

Will this padded work jacket restrict movement on site?

It is built specifically to avoid that problem. The shell uses a 4-way stretch construction, and the ergonomic raglan sleeve cut allows a full range of arm motion without the jacket pulling or riding up. The InsulatexPro insulation delivers 240g of warmth without adding unnecessary bulk, so the jacket moves with the wearer rather than working against them during overhead tasks or confined work.

How do you care for this insulated jacket to keep it performing over time?

Machine wash at a maximum of 30°C using a mild process and a liquid detergent suited to technical fabrics, which preserves the Texpel Splash Eco finish. Drip line dry only - do not tumble dry, iron, bleach, or dry clean. If water beading fades with use, it can be restored by tumbling the clean, dry jacket briefly on a low-heat setting, or by applying a PFAS-free DWR reproofing spray after washing.
