The Blåkläder 1845 XWARM underwear trousers are a warm base layer for working in severe cold. They are recommended for temperatures from -20°C to -35°C.
The 100% merino wool insulates well and wicks moisture away from the skin, helping you stay warm and dry through the working day. An elasticated waistband and cuffed trouser bottoms keep the layer in place under your work trousers.
