This padded hi-vis tunnel jacket is built for outdoor work in cold, wet and windy conditions where you need to stay visible. Battery-powered carbon fibre panels add warmth on top of the padded, fully lined construction.
You control the heat with a button at the chest, choosing from three settings as conditions change. The heat sealed baffle fabric and sealed seams help keep out wind and rain, and segmented reflective tape adds visibility in low light.
