Castelli Pro Thermal Head Thingy

The Castelli Pro Thermal Head Thingy has a tube construction that can be used in many ways. Slip over your head and wear it around your neck. Raise it to cover different parts of your face and your ears. Keep it at the top of your head like a beanie. The soft, stretchy Thermoflex insulates body heat and fits close to your head and neck so you can wear a helmet.
