Castelli Pro Thermal W Skully - Women's

What Makes the Castelli Pro Thermal W Skully Worth Wearing?

The Castelli Pro Thermal W Skully is purpose-built for cold-weather riding, constructed with THERMOFLEX fabric that traps heat efficiently without overheating during climbs or sustained tempo efforts. The women's-specific cut sits low on the ears and fits cleanly under any road or gravel helmet, staying put through the full ride without bunching or shifting at the brim. Full ear coverage extends far enough to block wind chill on fast descents without restricting peripheral vision, which matters when riding in a group or navigating traffic in cold temperatures.

The Skully layers seamlessly under a helmet or works as a standalone piece in milder shoulder-season conditions, with enough stretch to seal out drafts without squeezing uncomfortably around the head. Women's-specific cycling fit runs true to size and pairs cleanly with any jersey or jacket neckline without adding visible bulk at the collar. Machine washable and made in Italy to Castelli's construction standards, it holds its shape and thermal performance season after season. If you are building out a cold-weather kit, this is the piece you reach for consistently from October through March.
