Motorcycles are cool and when it comes to motorcycle sunglasses the short answer is they have to do both. KD's have been around for ever and have basically been making the same style biker sunglasses since the 70's.
When a customer asks me what are the best sunglasses for them, I always ask what kind of bike they own and what type of riding they do.
Because motorcycle sunglasses are really eye protection, I suggest you only consider sunglasses that have the manufactures name on them.
