Castelli Pro Thermal W Headthingy

The Castelli Pro Thermal Woman’s Headthingy is a versatile head piece that can keep a woman’s head warm in most outdoor sports. Use it as a cap to warm your head. Stretch it down to also cover your ears. Use its tubal construction to warm your neck. From your neck pull it up to also warm the lower part of your face and ears. Made with a Thermoflex fabric, the headthingy is cozy, soft and fits close so you can wear it under a cycling helmet.
