Yeah, they are big(not obnoxious). To list these for a "medium" face is a bit much, but if you can provide a med/lrg face, you will love these glasses! Great optics, huge field of view and the O Matter frames are superlight, comfy and strong.
The fit, airflow and styling of this helmet is great! I have POC Lobes goggles and they integrate very nicely. The audio jack in the earflap is something to be desired. Mine floats around and I have to search for it when plugging in. I don't know if this is isolated or a bigger problem.
