Title is a compliment.  Ray-Ban's seem to stagnate in terms of the trend towards active wear sunglasses.  This was the closest thing I found to a replacement for my Native Eyewear Dash Hardtop XP's.  I worried that they were a bit flimsier in the arm joints than is needed for use in hiking, biking and field work.  But thus far, no sign of that.  Good quality glass, nice case.  I'm happy with the purchase.
