This is basically just a Flexon frame with Nike branding on the temple. Which does give the wearer a great product in the end. Very lightweight and minimalistic. The metal really does flex quite well and holds up well over time. I’m an optician and sell frames from this brand over and over again. If someone desires to put new lenses in a Flexon brand frame after 2-3 years of wear, they usually can. I really only see cosmetic wear by that point not structural.
