Anyone familiar with Giordana's summer kit knows that the elements of fit and design that go into the Italian manufacturer's clothing are second to none. Items like the Silverline Roubaix Knickers carry this trend into the cooler months of the year. The layout of the panels describe a curved trajectory, conforming to the cycling position for a restriction free, low abrasion fit that takes some of the hardship out of riding in the cold. The key ingredient in the Silverline Roubaix Knickers is cleverly hidden in their name: Super Roubaix fabric. Super Roubaix is a soft, fleece lined material that insulates and breathes like merino wool, keeping your temperature in the green zone for long hours of winter base building. It wins out over wool in the stretch department, though, deforming and returning in ways that wool can only sheepishly dream of. The Silverlines also dream, with panels of ThermoDream fabric laid strategically throughout their construction where you'll benefit from more stretch and breathability instead of SuperRoubaix's focus on protection. The seat panels' hydrophobic treatment is one of our favorite features of the Silverlines, and it warrants special mention. It means that rain and road moisture have less of a chance to soak your chamois. There are few feelings in cycling that sink our spirits faster than being 40 miles from home in 40 degrees Fahrenheit with a frigid, soggy chamois. The included W. Nimbo O. F. chamois forgoes the usual discomfort of a cold weather chamois, using varied padding and a subtle surface texture to keep your weight where you want it and help transport potentially clammy moisture away from your skin. It's also designed with separate sit bone panels, so they can stretch and move independently of each other for uninhibited in saddle motion. The Silverlines are finished off with Silicone grip and elastic at the cuffs and reflective elements to help keep you visible in low light conditions.
