Crisp air, colorful foliage, and long, spooky dusks are just a few of the pleasures of cycling in autumn but they do come with falling temperatures. If you love the atmosphere of fall but aren't so hot on the cool weather, then you'll find that Capo's Women's Siena Roubaix Knickers strike the right balance between tissue thin summer shorts and heavily insulated winter tights. The Siena Roubaix Knickers are named after the Thermo Roubaix fabric used in their construction. Thermo Roubaix is made up of hollow core fibers, which effectively maximizes the surface area of the material. This increases the material's wicking properties and creates countless micro pockets of trapped air to act as insulation basically the same principle that makes Merino wool such a quality insulator. The benefits of Thermo Roubaix are also evident in the Sienna Roubaix Tights' elasticity and abrasion resistance. The Veloce HD EIT Insert is provided by Elastic Interface, a division of chamois giant CyTech. This women specific chamois is channeled for maximum airflow, boasts antibacterial properties, and is designed to stretch and move with you whether you're hammering through cold weather intervals or spinning out base miles. The abbreviated fit of the knickers also recommends them for short, hard efforts in cool weather like a 'cross race or in conditions where you want some extra insulation but full length tights would be overdoing it. The Women's Capo Siena Roubaix Knickers are available in four sizes ranging from X Small to Large in the color Black.
