The Castelli Pro Thermal Skully Cycling Skull Cap will keep your head warm and toasty on your cold winter rides. It is made for warmth, however it does have excellent wicking which helps keep the skull dry. It is very lightweight so that it does not feel bulky under your helmet. The raw cut edge makes it a comfortable fit which will not interfere with the straps or helmet cage. The Thermoflex fabric is surprisingly warm.
