It's not always easy to climb out of your bed on a chilly fall day and mentally prepare yourself for an early morning bike ride. In fact, it can be downright daunting. By combining warm, sweat-wicking fabrics and body-contouring fit, the Giordana Silverline Sport Women's Tights make it just a bit easier to follow through on the commitment you made the night before.Giordana constructed the Silverline Sport 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.Inside the Silverline Sport Tights you'll find Giordana's women's specific Nimbo-W 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 to promote excellent ventilation. The Silverline Sport Tights are designed to fit best when you're on the bike; as such, they were constructed on a curve to support a woman's natural riding position. The tights are secured at the waist with soft elastic and an internal drawstring, and 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 Giordana Silverline Sport Women's Tights come in sizes X-Small through X-Large and in Black.
