I love my Lautners! I have a black XL pair and an original whiskey color. The style is refined, lens quality is very nice and resists scratching effectively. I work in construction and frequently go in and out the build so am taking the shades on/off repeatedly each day, which means I frequently drop them or they'll fall out my sweatshirt pocket while I'm on a ladder leaning over etc. and they hold up great. Frame material and weight is solid yet flexible as needed, honestly Kiaura just nails the product. The CR39 lenses are excellent. I've also communicated with their team who were insanely fast at responding and delivering my order etc. Going to buy more as gifts!
