This merino wool crewneck baselayer is a long sleeve top for keeping you warm and dry during physically demanding work. It insulates while drawing moisture away from the skin, which helps you stay comfortable as your effort levels change through the day.
The lightweight merino and polyester blend suits wear in every season. Antimicrobial, anti-odour properties keep it fresher over long shifts, and the durable fabric is built for repeated use.
