The material composition, predominantly featuring merino wool, along with the presence of artificial silk (lyocell) and polyester, ensures not only excellent thermal insulation but also quick-drying capabilities and flexibility. The elastane added to the blend provides additional stretch, allowing freedom of movement during any activity. The long sleeves of the thermal t-shirt are an added advantage, providing protection against the cold while not restricting movement.
