PERFORMANCE QUATRO SUNGLASSES: Photochromic

I'm a concreter and can testify they do not scratch like all the others when you clean concrete off them evan with your shirt. And they are tough! They've saved me from alott of concrete splatter and 1 12mm piece of rear that did leave a minor scratch but that's too be expected. The only thing I couls think of to better this amazing product is maybe a O ring around the frame between the components as you can't get in there to clean that part

Excellent. Best glasses I’ve owned. They live on my face.

Like the slick style and photochromic is next level
