The 3/4 Advantage: Lightweight Design for Active Professionals
The DX402 3/4 trousers mark a breakthrough in mobility for active worksites. Their shorter cut enhances airflow and leg movement, making them perfect for warmer climates or indoor operations requiring dynamic activity. Crafted from Portwest’s 4X stretch fabric, they adapt naturally to movement, preventing restriction while climbing, crouching, or operating machinery. Despite their light construction, they maintain the durability and protection associated with the DX4 series. Hi-vis contrast panels and retroreflective heat-applied tape ensure Class 2 visibility, keeping workers safe across variable lighting conditions. Whether used in logistics, road maintenance, or construction, the DX402 offers the flexibility professionals need without compromising on protection or performance.

Engineered for Movement: Stretch Fabric and Ergonomic Fit
At the heart of the DX402 Hi-Vis Trousers lies Portwest’s exclusive dynamic 4X stretch fabric. This innovative blend of polyester, cotton, and elastane allows unrestricted motion in every direction. Articulated knees and a contoured waistband follow the body’s natural movement, reducing fatigue during long workdays. The reinforced crotch and triple-stitched seams add durability where it matters most. Side ventilation panels enhance breathability, and the 3/4 length design keeps the legs cool during physical exertion. These trousers are a direct response to the needs of modern workers — lighter, stronger, and smarter PPE that adapts to the pace of daily operations.

Practical Utility: Designed with Function in Mind
Functionality defines every detail of the DX402. Multiple cargo, ruler, and zipped pockets keep tools secure, while reflective trims maintain visibility even when partially obscured by harnesses or tool belts. The trousers feature removable holster pockets, adding adaptability for workers who switch between light and heavy-duty tasks. Reinforced knee zones and abrasion-resistant panels increase lifespan, while elasticated waist inserts ensure a perfect fit for all body types. When paired with a DX438 Coverall or EV448 Trousers, the DX402 completes Portwest’s modular DX system — a collection designed to deliver maximum efficiency and protection for modern worksites.

Hi-Vis Safety: Certified Confidence in Motion
Every pair of DX402 trousers meets EN ISO 20471 Class 2 standards for visibility and safety. Reflective segments are heat-sealed for flexibility and durability, eliminating the stiffness common in older stitched bands. This ensures visibility from all angles, even when working in motion or low light. The fluorescent outer fabric resists fading under UV exposure, maintaining brightness and safety compliance for years. The contrast panels, strategically placed along the knees and thighs, prevent stains and enhance visual distinction. When combined with upper garments from the hi-vis clothing collection, these trousers form a fully certified PPE set suitable for any European outdoor industry.

Breathability and Climate Control: Designed for Heat and Motion
Unlike traditional work trousers, the DX402 is designed for optimal temperature regulation. The breathable stretch fabric, coupled with 3/4 leg ventilation, ensures that heat dissipates naturally, even during extended shifts under the sun. The inner lining wicks moisture away from the skin, keeping the wearer dry and comfortable. This makes the DX402 particularly useful in industries like road construction, warehousing, or utilities — environments where movement, agility, and cooling are essential. The 3/4 cut also prevents fabric interference with boots or kneepads, enhancing stability and preventing snag hazards.
⸻
Built for Longevity and Value
Durability is central to Portwest’s engineering philosophy. The DX402 3/4 Hi-Vis Work Trousers offer outstanding longevity thanks to abrasion-resistant materials and triple-stitched seams. Reinforced stress points and a colorfast outer fabric ensure professional appearance and structural integrity even after months of daily use. The easy-care design supports frequent washing without losing reflective brightness or stretch quality. For companies managing large teams, this means lower replacement costs and higher satisfaction — a long-term investment in safety and reliability. By ordering directly from Optimum BHP, businesses can also customize trousers with logos or embroidery, creating cohesive, professional uniforms for on-site crews.
⸻
The DX4 System: Innovation Across Seasons
The DX402 is part of Portwest’s modular DX4 system, a lineup that includes jackets, coveralls, and trousers engineered for layered protection. In winter, workers can switch to the DX438 Coverall or insulated models, while in transitional seasons, the DX402 offers unmatched agility. The series exemplifies Portwest’s approach to practical PPE — every piece designed to interlock functionally, from reflective alignment to ergonomic fit. This ecosystem gives employers flexibility to equip their teams year-round with consistent quality, safety certification, and modern aesthetics.
