I bought these because they look so badass.
Great field of view due to the ridiculously awesome large lenses. The optics are very good, not phenomenal.
Can't change lenses without smudging, but with good quality wipes it's easy to clean them up.
Decent glasses but not really worth the price tag it commands. Both the S2 and Speedcraft are unique, however, build quality and optics are far behind Smiths and Oakley.
I liked the color scheme and look of the glasses but in the end they don't fit on my face properly and there is no peripheral vision. My go to pair are still the Oakley jawbreakers.
