Our Nano Flex 3G fabric is the result of a decade of development. It's our best all-around fabric for winter tights: warm, stretchy, luxuriously soft, highly breathable and on top of that it features our proprietary third generation of nanotechnology water-repellent finish. While other companies are using simple chemical water-repellent finishes, we create a nanotechnology mechanical repellency to enhance a chemical DWR finish. You stay drier and more comfortable.
