A pair of aviator sunglasses can't be much lighter than these. Created for an active lifestyle, perfect for minimalists. With black rimless polarized lenses and thin titanium frames, the weight of these sunglasses is only 8.7g! Titanium is a very lightweight metal, yet extremely strong. In fact, it is known as the strongest metal for its weight. The extraordinary design lacks hinges, but the temples can be bent and easily stored in a case that comes with them. Lenses are polarized and reduce glare well.
