I use these for mountain biking and love them. They are not too dark, but still provide lots of protection from the sun, and they are large enough to protect you from rocks, bugs, and the occasional tree branch. Currently I use the lenses that came in them, but you do get 3 other options. Clear, yellow, and black. I cannot speak for those 3 yet because I love the multi color reflective lenses. Also the frame is super light and comfortable, and it's unique look is incredible. I did have to use customer service for an issue I had and it was resolved same day. Overall 5 stars for the glasses and 5 stars for the company's customer service. I will be purchasing more glasses from them in the future.
