The Portwest B184 Merino Wool 1/4 Zip Baselayer Top is a lightweight thermal layer for year-round work. Its high merino wool content provides insulation, helping you stay warm when conditions turn cold.
The fabric draws moisture away from the skin and lets it breathe, so it suits active work. Anti-odour properties help it stay fresher over a long shift. A 1/4 length front zip lets you adjust ventilation as you warm up or cool down.
