We made this tight for serious winter riding. That means keeping you protected and comfortable in the widest possible range of conditions. Easy to say, but harder to actually do. The main part of the tight uses our Nano Flex 3G fabric, the third generation of our proprietary nanotechnology fabric treatment that adds a high level of water repellency without affecting the breathability, stretch or warmth of the fabric. You get a highly stretchy, compressive fit that moves with you, for luxurious comfort with the best protection on the market. We add Nano Flex Xtra Dry panels to provide a bit more wind protection and warmth in the front and over the thighs. It's not only about the fabrics: anatomical patterning gives a bend at the knee and the hip, while the seamless bib straps lie flat so you hardly notice them. Our generously padded women's-specific Progetto X2 Air seamless seat pad make long rides more comfortable, and you have multiple reflective panels to keep you visible. We've designed this as the go-to tight for a full winter's riding.
