Portwest DX481 DX4 Hi-Vis Lightweight Stretch Work Jacket
Portwest DX481 offers a lightweight alternative to a padded work jacket when freedom of movement matters. Portwest identifies this DX4 garment as a hi-vis base layer, designed to work within a clothing system that can be adjusted as temperatures change.
The main fabric combines 92% polyester with 8% elastane, with nylon/elastane contrast panels. Four-way stretch and raglan sleeves support movement through the shoulders and arms, while the active fit limits excess fabric.
Segmented heat-applied reflective tape follows the garment’s movement. Elasticated cuffs and thumb loops help retain sleeve position, and internal pockets provide space for small work items.
Astral Hygiene lists orange/black and yellow/black in sizes S–6XL. The manufacturer specifies EN ISO 20471 Class 2 visibility, with RIS 3279 TOM Issue 2 applying to orange only. Keep the required visibility exposed when adding outer layers.
