Pinlock use - who uses 'em

[Stichill_imp]

I've had Pinlock. They work well in cold weather and cool, humid weather. You have to be prepared that they scratch rather easily and need to be replaced from time to time. You're not supposed to wear them at night. I did one time and I did not think it impaired visibility. They aren't great in a dust storm...sand particles will get inside them (happened to me in Death Valley).
