Keep Ya Head Thingy Warm
Neck warmer, cap, face mask, balaclava or all four? The Castelli Light Women's Head Thingy is a tube of 100% Polyester jersey fabric employed for maximum moisture management that will not only keep your neck protected from the early morning chill but will be equally happy if worn on the head under your helmet. The head thingy can be worn in mildly cool to warm weather. Its nearly weightless construction won't weigh you down like traditional bulky head pieces.
