I had no idea I had a smallish face until I tried these on and they fit perfectly. I have tried so many goggles, but really wanted a pair with the sensor lens for snowy conditions (my other goggles are Oakley A-Frames with polarized VR28 lenses, which fit well and are completely flush with my GIRO G10 helmet and did not fog AT ALL in all sorts of conditions) because I found it hard to see with my A-Frames when weather took a turn for the worse. I tried Electric EG-1s and they pinched my nose considerably - enough for me to return them. These I/OS's do nothing of the sort, and allow me to see so much.
The only thing wrong is, they did fog up on me while my A-Frames never did, even with balaclava on. But it wasn't *too* bad - nothing that I couldn't deal with (and the fog dissipated pretty quickly). Also, I changed the lenses out during lunch and somehow didn't snap in the nose part correctly and snow flew into my goggle, but that's my fault.
All in all, glad I found these on tramdock. I think they're a keeper. The ignitor mirror is a great mirror - can't see my eyes AT ALL in all the pics I took. And the sensor mirror is every bit as awesome as people have said in snowy conditions - I put them on and everything was suddenly enhanced.
