“I have owned several Smith products over the years and I have always loved them. The Wildcat sunglasses look stylish, have great coverage and they are really light weight. Unfortunately, after about 4 months of use, I have two issues with these glasses. 1. I cannot keep them from sliding down my nose while mountain biking. I have tried both nose positions with no change and I have also tried aftermarket nose grips which do not seem to help either. 2. The photochromic lens seemed to get stuck in it's darkest shade (full sun mode). Yesterday on my after work ride, the trail was in and out of sunny areas and shaded woods, but the lens never changed from dark to light. That seemed weird to me because on previous rides the lens did seem to change as described in other reviews??? As mentioned before, I like the style and coverage so I will keep trying to make these work and fit. Thank you Smith!”
