Castelli Viva 2 Women's SkullyThe Castelli Viva 2 Women's Skully is here to help keep your head warm while riding in cold weather conditions. It's constructed from Thermoflex fabric, which makes it warm, soft and stretchy for maximum comfort over long hours of riding. The raw-cut edge lies flat and doesn't bunch up under the helmet, so you'll barely notice it. It also features an opening on the back for a ponytail, making it less of a pain to put on and wear.FEATURESThermoFlex is warm, soft stretchyRaw-cut edge lies flat and doesn't bunch under helmetOpening at back for ponytail | Castelli Viva 2 W Skully Women's in Dark Steel Blue
