This men’s long-sleeve thermal top is built for work in severe cold, with a recommended temperature range of -20°C to -35°C. It is made from heavyweight Merino wool that insulates well and draws moisture away from the skin, helping you stay warm and dry through long shifts outdoors.
The zip neck lets you vent heat when you are working hard and close up again when you stop. An extended back keeps your lower back covered when you bend or reach. It has a two-tone look with contrasting seams.
