Our Nano Flex 3G fabric is the result of ten years of development. It’s our best all-round fabric for our winter tights. It’s warm, stretchy, deliciously soft, highly breathable and features our patented third generation water repellent finish derived from nanotechnology. While other brands use simple chemical water repellent finishes, we’ve created a mechanical water repellency derived from nanotechnology to enhance a chemical DWR finish. You stay drier and more comfortable. Although these tights feature our latest water repellent technology, they’re not just rain tights. The fabric is perfectly suited to dry conditions, and the anatomical cut with reduced seams makes them extremely comfortable. These tights feature the KISS Air2 pro chamois with mesh straps and zipped ankles. These are tights that excel in all weather conditions!
