Heat-insulating, technical, sporty – with high comfort: The UYN® Ambityon Underwear Pants Long impress with effective climate management and optimal fit. Their material, Natex, a nylon fiber made from 100 percent biological sources, feels soft and dries extremely quickly. In combination with Coolvent, three-dimensional channels for optimal air circulation, the pants absorb sweat and keep the skin dry. At all times, winter sports enthusiasts are protected from the cold thanks to Heatmemory. This feature provides high insulating properties specifically designed for athletic activity on cold days – especially at the exposed, heavily stressed knees. There, thanks to Durafit processing and material, high durability and heat insulation are ensured.
