The EV4 Hi-Vis Stretch Detachable Holster Class 1 Trousers represent a significant advancement in technical workwear design. Engineered for the modern professional who requires both visibility and unrestricted movement, these trousers move away from traditional, restrictive fabrics in favour of a highly ergonomic, multi-fabric construction. By integrating targeted laser-cut ventilation with advanced stretch materials, they ensure the wearer remains cool and comfortable during high-intensity tasks without compromising on durability or safety standards.
The performance of the EV4 trouser is rooted in its sophisticated material composition. The main body utilizes Titanmill Ultra Stretch, a medium-weight fabric that offers a superior strength-to-weight ratio. For added resilience, Titanmill Pro Ripstop panels are strategically placed to resist tearing and abrasion in high-wear areas. The addition of CorePro Armour—a robust blend of nylon and polyester—provides a further layer of protection at the knees and hems.
The design prioritises the user's silhouette in motion. A high-rise back waistband, complemented by side elastication, ensures that the trousers remain securely in place even when crouching or stretching, providing continuous coverage and preventing the 'gap' often found in lesser workwear designs.
We provide these trousers as a non-customised item to ensure the integrity of their technical features and safety certifications. The EV4 range utilizes complex, multi-layered stretch fabrics and precision laser-cut ventilation holes; applying heat-pressed vinyl or heavy embroidery can inadvertently block these vents or damage the elastane fibres that provide the garment's flexibility. Furthermore, as a Class 1 Hi-Vis item, any unauthorised modification could potentially affect its compliance with safety standards.
These trousers are ideally suited for tradespeople operating in environments that require high-visibility protection, such as logistics, light construction, and surveying. The ergonomic design makes them particularly effective for those who spend significant time kneeling or moving through tight spaces, where freedom of movement is as critical as visibility.
Since 1976, MyWorkwear has been at the forefront of the UK's technical clothing industry. Based in Telford, Shropshire, we have decades of experience in assessing the performance of workwear. We select products like the EV4 because they meet our exacting standards for durability, innovation, and professional appearance, ensuring our customers are equipped with the very best tools for the job.
Given the stretch nature of the Titanmill fabric and the elasticated waistband, these trousers offer a flexible fit. However, we recommend selecting your standard waist size to ensure the knee pad pockets align correctly with your joints. For those working in warmer environments, the laser-cut vents work most effectively when worn with moisture-wicking base layers rather than heavy cotton undergarments.
To maintain the high-performance characteristics of these trousers, we recommend a domestic wash at a maximum temperature of 40°C. This temperature is sufficient to remove workplace dirt while protecting the elastane fibres and the reflective properties of the hi-vis tape. Exceeding this temperature may lead to a loss of elasticity over time.
Under no circumstances should you bleach, iron, or tumble dry this garment. High heat from an iron or tumble dryer will damage the synthetic fibres and the specialized CorePro Armour reinforcements. Drip line drying is the safest method to preserve the shape and technical integrity of the fabric. Please note that the garment is certified for a maximum of 25 washes to ensure the hi-vis components remain within safety tolerances.
