I've had a pair of MJ Hapunas for 4 years that I bought for fishing and driving. Great lenses, but they don't fit very well under my ff helmet. So for riding, I wear Wiley X Romer II's. Fit great, interchangable lenses, very durable, comfortable and safe.

 

You guys bring up a good point about the shatter resistance of the MJ glasses. Perhaps I will start looking for a pair of Wiley's.
