Nothing against Proetus, just guess its what your looking for in a goggle system.
Have a look at the JT Flex 7 and Flex 7 IZE goggles as they are very good in respect to comfort and air circulation (no fogging).
However, V-force are better as far as taking out the lenses, but thats not a regular chore anyway, they just need checking every now and again.
Have a look around for a deal on Classifieds.
