Well, as a matter of fact, Rudy project is an Italian brand which focuses on a wide range of products, including sports wear and sunglasses for outdoor activities. And it would not be hard for you to spot them over the Internet. I should recommend Ebay and Amazon to you, maybe you will regard them as websites full of fakes, however, it depends on your ability to tell authenticity. Meanwhile, you might as well contact their hotline to see where you can buy.
