The Portwest DX4E40 DX4 Evolution Stretch Detachable Holster Trousers are the toughest trousers in the DX4 collection. They are built for demanding work where you carry a lot of tools and spend much of the day kneeling, crouching or squatting.
Developed with tradespeople, they combine heavily reinforced knees and holsters with a stretch fabric and a cut designed around movement. The holsters detach when you need a cleaner, lighter set-up.
Key features
- 20 pockets, including detachable holsters that hold 7kg for 24 hours, so heavy tools stay close to hand
- Kneepad pockets let you fit knee protection for floor-level work
- CorePro™ Indestructible Eco knee reinforcement, rated to 130,000 Martindale abrasion rubs, resists wear where trousers usually fail first
- Titanmill™ Pro Stretch Eco fabric gives up to 30% 4-way stretch for crouching, squatting and seated work
- Wide gusset, vented back knee and low-bulk panelling help movement and airflow, with seams placed to reduce restriction
- Reinforced holster pockets, ripstop at high-wear areas and triple-stitched seams throughout add durability
- Rule pocket with a concealed knife button that flexes away as you bend
- Extendable leg length from 31″ to 33″ lets you adjust the length to suit
