Castelli Viva Thermo Headband

For those days when a full skully would be a bit of overkill, but the wind is still nipping at your ears, the Viva Thermo Headband makes a perfect go to. The fleece lined ThermoFlex material that comprises it is warm and soft, stretching easily to accommodate a wide variety of domes, yet it's also especially breathable and never lets you overheat. It's raw cut edges don't bunch and won't apply pressure points to your head under your helmet, making this light cap something you'll almost forget it's there until you take it off, of course.
