Giordana designed its Silverline winter apparel to offer much of the warmth and body-contouring fit of its top-end FormaRed Carbon line without the sticker shock. As such, Silverline clothes appeal to a wide range of riders--from amateur road racers dedicated to getting the jump on the competition to cyclocross fanatics. The Giordana Silverline Windfront Men's Bib Tights are the warmest tights in the Silverline family due to the added wind-blocking thigh panels in front, and they have plenty of features to ensure that you stay comfortable during the chilly months. Giordana constructed the Silverline Windfront Bib Tights out of Super Roubaix and ThermoDream fabrics. Super Roubaix, used in the front of the tights, is a stretchy, muscle-compressing fabric that's smooth on the outside and brushed on the inside for insulation against the cold. ThermoDream makes up the rear panels of the tights; it's a similar insulating fabric that fits like nylon and spandex, but is heavier for cold-weather applications. WindTex panels cover the thighs, providing a barrier between you and the elements without negatively affecting breathability. The bib straps are made of two different mesh materials for proper temperature regulation.Inside the Silverline Windfront Bib Tights you'll find Giordana's Nimbo O.F. chamois. This seamless, single-piece insert has foam padding of varying thicknesses and densities to ensure comfort while minimizing bulk. It's elastic, so it moves and stretches with you as you ride, and then returns to its original shape when you're done. The outer layer of the pad is perforated for excellent ventilation.The Silverline Windfront Bib Tights are designed to fit best when you're on the bike; as such, they were constructed on a curve to support the natural riding position. The bib tights are secured at the ankles by silicone grippers. Additionally, the ankle cuffs have locking zips. Highly visible reflective accents provide safety when riding in low-light conditions. The The Giordana Silverline Windfront Men's Bib Tights come in sizes Small through 3X-Large and in Black.
