As the name implies, Flexon frames are flexible, break-resistant, and are made to last. Touted as “the memory metal” these specs are designed with a unique titanium alloy that’s corrosion-resistant and can return to its original shape even if you bend, twist, and squeeze it. We’re so stoked about how comfortable and ultra-lightweight these are since it’s 25% lighter than typical metal and eases the strain on the ears and nose. You can hardly tell they’re on.
