Aclima HotWool is made from terry wool, and is our warmest woolen underwear. This is a clear favorite for those who work outside. Terry wool is a mixture where wool is the main component, and it is mixed with other fibres to make the garments thicker and more hardwearing than our pure wool garments. The loops on the inside of the clothes ensure fantastic insulation by creating a layer of air. Its durability, great insulating capabilities as well as the fact that it does not itch has lead the Armed Forces to select this quality fabric. Aclima Sports Top has cups in soft, itch-free terry wool lining made from merino wool. The Sports Top is perfect for those who maintain a high tempo, and enjoy being outdoors even in the winter. An important product to keep you warm when you need it the most.
