The cold crawl of winter might be a relief from the heat, but it also requires layering up when you're out on a ride. Training in cold weather calls for more than what leg warmers can provide, so when the freeze sets in, slip into a pair of the Giordana Silverline Women's Bib Knickers. These cold weather knickers utilize Giordana's winter-weight fabrics and superb construction to provide superior warmth. A flattering fit and a women-specific bib strap design will make these your go to knickers all winter.

The Silverline Roubaix knickers are engineered using Giordana's Women's Contour Fit process and are constructed to fit a myriad of women's bodies. Since warmth and comfort are the two biggest concerns with knickers, Giordana uses a combination of winter-weight materials for moisture transfer and heat retention. The Super Roubaix micro fiber has an interlocking, brushed-knit inner-layer that plays host to an incredible stretch. It's also highly breathable, with enhanced moisture wicking properties that strip sweat from the skin while insulating against cold air. Super Roubaix also has a slight compressive element that essentially massages your muscles, helping to prevent fatigue. The back of the legs and seat panels are made from Thermo Dream. This winter-weight micro fiber stretches with your movements and has an interlocking knit to trap heat. Together these fabrics work to keep your temperature regulated and your muscles protected from cold air.

The bib straps are made of Naxo and PowerNet Mesh for heightened temperature regulation and breathability through the back of the bib straps. Designed to not interfere with your other layers, the bib straps rise high on the back, and run along the sides of your chest, expanding as they meet the knickers.

The Silverline Bib Knickers also come with the Women's Nimbo O.F. chamois. A female-specific chamois, the Nimbo is designed to keep you feeling comfortable over long distances. It uses a variable density construction, with thicker portions of foam where you need it the most -- under your sit bones. The top layer utilizes a slightly textured pattern to move moisture away from the skin to the outside of the chamois for evaporation. The sides of the chamois, and glute panels, allow for flexibility and protection, whether you're sitting in the saddle or standing up for a sprint.

The knickers sit below the knee and are held in place by an elastic gripper that runs along the bottom hem. Reflective piping along the front and back of the knickers adds visibility in low-light conditions.

The Giordana Silverline Women's Bib Knickers are available in the color Black Reflective and in five sizes from X-Small to X-Large.
