Mach 1: Blue PhotoChromic

Great pair at a great price

Have been wearing these for the last couple months while on my mtb and fat bike and have no complaints at all. They've taken a few branches to the lens and no scratches or damage on the lens or frame. The photochromatic feature works very well and seems to tint more gradually than other brands. These really seem to vary the tint depending on lighting conditions. Not just fully tint the second you go outside. I plan to grab another pair in a different color soon. For the price I really don't think you can go wrong

Really solid value!
