Thin balaclava starting from a few days ago until we get near freezing weather when I'll add a second balaclava some days. Forgot it today and missed it, we're definitely now down to the temps here where I want it (below 50). Sometimes I'll wear the headband I usually wear the rest of the year to keep sweat out of my eyes as an additional wind shield if I find my forehead getting cold and I'm already wearing a thin balaclava.
