The Portwest EV401 EV4 Hi-Vis Expedition Parka Jacket is built for demanding outdoor work in severe cold, wind, rain and snow. A mechanical stretch waterproof shell moves with you, while a high-loft Insulatex™ Pro filling provides serious warmth.
The longer, dropped back hem gives extra coverage when you bend or crouch. Segmented reflective tape keeps you visible, and ten pockets give you plenty of space for tools, phone and personal items.
