Man I would LOVE to see the looks on peoples faces with the skull mask. What the hell do you do that you have that stuff at the office and people still will sit in the adjacent cubes?
My problem is fogging my glasses.. The baklava's when pulled up over the nose direct your breath right at the back of the lenses. No fun.
For a full face to work it would need something that would go below your eyes to direct your breath away from the lens and glasses.
I'm picking up ski or motor X goggles that will fit over my glasses and seeing how that works soon. If you are looking for safety then goggles with a BMX helmet would probably be a good set up.
