Portwest EV4 Hi-Vis Stretch Detachable Holster Class 2 Trousers

The Portwest EV4 Hi-Vis Stretch Detachable Holster Trousers represent the pinnacle of the EV4 collection, combining cutting-edge fabric technology with ergonomic design for professionals who demand unrestricted movement without compromising safety. These trousers utilise the targeted placement of laser-cut ventilation to provide maximum airflow when working in demanding conditions. The construction incorporates Titanmill Ultra Stretch fabric—a high-performance blend of 92% Nylon and 8% Elastane—delivering exceptional 4-way stretch that moves naturally with the body throughout the working day. With 17 pockets including detachable holster pockets, pre-bent knee pad compartments, and a rule pocket, these trousers offer comprehensive storage for every tool and device a tradesperson needs at hand.

Key Features

4-Way Stretch Titanmill Ultra Fabric The shell fabric is engineered from Portwest's proprietary Titanmill Ultra Stretch material, a technically advanced blend of 92% Nylon and 8% Elastane at 230g weight. This fabric provides genuine four-way stretch capabilities, allowing the trousers to move naturally in every direction during bending, kneeling, climbing or crouching. Unlike conventional workwear that restricts movement and creates stress points, these trousers flex with the wearer, reducing fatigue over long shifts and eliminating the constant need to adjust clothing.

Laser-Cut Ventilation System Strategic laser-cut ventilation holes are precisely positioned to maximise airflow around key heat zones without compromising structural integrity. This engineered ventilation system helps regulate body temperature during physically demanding work, reducing perspiration build-up and maintaining comfort throughout extended wear. The laser cutting technique ensures clean, durable apertures that won't fray or expand over time.

CorePro Armour Reinforcement High-wear areas are reinforced with CorePro Armour panels—a heavy-duty 260g fabric blend of 72% Nylon, 16% Polyester and 12% PU. This reinforcement protects the lining at stress points and extends garment life significantly. The detachable holster pockets also utilise CorePro reinforcement, ensuring they withstand the weight and abrasion of heavy tools without premature wear.

Detachable Zip-Off Holster Pockets The holster pockets attach via robust zips, allowing them to be removed when not required. This versatility means the trousers can transform from fully-loaded work trousers to a cleaner silhouette for tasks that don't require tool storage, meetings, or travel. When attached, the holsters provide secure, easily accessible storage for power tools, hand tools, fixings and accessories.

17-Pocket Storage Configuration An extensive pocket system addresses every storage requirement: generously sized front pockets for frequently accessed items, multi-functional zip thigh pockets for secure storage of phones, pens and small tools, a dedicated rule pocket for folding rules, a concealed phone pocket, and the versatile holster pockets. This comprehensive layout eliminates the need for separate tool belts and keeps everything within easy reach.

HiVisTex Pro Segmented Reflective Tape Lightweight, flexible HiVisTex Pro segmented reflective tape provides enhanced visibility without restricting movement. The segmented design allows the tape to flex naturally with the body, preventing the cracking and stiffness associated with traditional continuous tape. Heat-applied segmented reflective tape and reflective print add further visibility elements, ensuring workers remain conspicuous from all angles in low-light conditions.

Pre-Bent Adjustable Knee Pad Pockets The knee pad pockets are engineered with a pre-bent shape that matches natural kneeling posture, providing superior comfort when working on the ground. Top-loading access allows quick and easy insertion or removal of knee pads without removing the trousers. Two positioning options accommodate different preferences and working heights, and the pockets are certified to EN 14404 Type 2 Level 0 when used with Portwest S156 knee pads.

High-Rise Back Waistband with Side Elastication The elevated rear waistband prevents exposure when bending forward—a common complaint with standard workwear. Side elastication provides a secure, comfortable fit that adjusts naturally to body movement without requiring belt tightening. This combination ensures consistent coverage and comfort across all working positions.

Stretch Crotch Gusset A dedicated stretch gusset in the crotch area provides maximum flexibility and dramatically reduces stress on seams during dynamic movements. This construction detail significantly extends garment life by distributing tension across the gusset rather than concentrating it at seam intersections.

FlexiHem™ Ankle Adjusters The proprietary FlexiHem™ system secures the trouser hem at the ankle, holding it firmly in place to reduce entrapment hazards around machinery or obstacles. Combined with inner boot clips that secure the trouser to footwear, this prevents riding up during movement—keeping the reflective tape in optimal position for visibility.

Triple Stitching Throughout All seams feature triple stitching for maximum durability, providing reinforced construction that withstands the rigours of daily industrial use. This stitching technique distributes stress across three thread lines, significantly increasing tear resistance and extending garment life.

UPF 40+ Sun Protection The fabric provides UPF 40+ protection, blocking 98% of harmful UV rays. For outdoor workers exposed to sun throughout the day, this built-in protection reduces cumulative UV exposure without requiring additional sunscreen application—particularly valuable for construction, utilities and outdoor maintenance roles.
