Castelli Men's Tutto Nano Bibshort
The Nano Flex 3G fabric is the result of a decade of development. It's their best all-around fabric for winter tights: warm, stretchy, luxuriously soft, highly breathable and on top of that it features their proprietary third generation of nanotechnology water-repellent finish. While other companies are using simple chemical water-repellent finishes, Castelli created a nanotechnology mechanical repellency to enhance a chemical DWR finish. You stay drier and more comfortable.
The fabric also makes for a great dry-weather tight, and the reduced-seam anatomical cut makes it extremely comfortable. They use the pro-level KISS Air2 seat pad along with a mesh bib and zippered ankles.
