You'll either have to do the break in in stages or wear a bandanna. It killed my forehead after about 2 hours. It evacuates air well but doesn't bring in much cool air. The chin thingy will vibrate like a mother fucker if you move your head wrong. I probably won't use it seriously till temps come down or I hit the grave yard shift. Darker visors are $20 and come in Dark smoke. I'll get one soon.
