Hope nothing goes wrong

Smith no longer repairs items or offers replacement parts. I would recommend purchasing from a company that supports sustainability and their customers.

As close as you can get to do-it-all glasses road and mtb

Great field of view, style on point, and a big enough range in tint to keep you able to see in a wide variety of conditions. The photochromic is dope on days where lighting changes which happens all the time in Colorado where I'm at. I also took them MTB in Moab and they did just as well there. The light transmission minimum isn't quite as low as my other sunglasses so looking through these is noticably brighter but I didn't have any issues with eyestrain or glare while I was out in the desert. Bonus points: Smith support also got back to me within a hour when I emailed them some questions. 10/10

No tears

These puppies cut the wind on fast descents, even better than the wild cats, no tears! And field of view is terrific! Style is on point too
