i went from a $50 pair of Siroko, to a prizm Jawbreakers, and although it is not a fair comparison, I really like my Jawbreakers. I sweat a lot and the venting on the Jawbreakers keep the lenses much more clear. I also like the clarity of the lenses, which provide more details on the road. It’s way better than polorized lenses which only darken what you see.
