The TYTUS COMBO Titanium Self-Protecting Sunglasses prove that long-lasting sunglasses can be stylish. Both scratch-resistant and crash-proof eyewear, these glasses will last. When you head out on an adventure, you want sunglasses that both look cool and can handle your lifestyle. These titanium sunglasses do the trick. With a patented, lifetime-guaranteed locking system, these glasses protect themselves. The rotating frame protects its scratch-resistant lenses by the hinges when they’re not in use. And though they use high-quality materials, these scratch-resistant sunglasses weigh just 20 grams. Handmade in Italy, these long-lasting sunglasses use Zeiss lenses. And with two frame options, they even come in more than 200 variants. Choose your frame style and color, and then you can select from a variety of lenses or add your own prescription lenses.
