Castelli Tutto Nano

By the way, also fantastic in the rain

Our Nano Flex 3G is the result of ten years of continuous research. It is our best all-round material for winter pants: warm, elastic, incredibly soft, highly breathable, and also the third generation of our water-repellent finish with nanotechnology. While other manufacturers only use chemical water-repellent processes, we developed a mechanical, water-repellent treatment with nanotechnology that, together with the DWR finish, significantly improves moisture protection. You stay drier and feel more comfortable. Despite this benefit, the Tutto Nano pants should not be labeled as just rain pants. Comfortable material, anatomical cut with reduced seams also guarantee an excellent pair of pants in dry conditions. Mesh straps, KISS Air2 seat padding, and leg zippers are, of course, essential. The pants that meet every demand.
