This is my second pair. The best sunglasses ever. Can be used by both genders. These are probably the biggest size on the market . Absolutely love them. Actually protect from the sun and do not obstruct vision ( even if you have to run inside). Amazing deal. I don't claim to be an expert in authenticating this product , but it appears true Porsche. If it is a fake , it is better than the real thing . NYC Porsche store told me these were legit. The replacement lenses from the authentic Porsche store fit the frames perfectly . That's also one of the best features of the these sunglasses . If you scratch or brake the lenses , can easily flip into replacement lenses. Also, nice to have an option to change lens colors. These come with 2 pairs of lenses.
