You never really know what you're gonna get when you can't try on a pair of sunglasses, or hold it in your hand to judge quality. Based on the reviews I decided to give it a shot and I'm glad I did. Material quality is great, the glasses themselves are sexy and I love the rubber material on the nose and ear pieces to keep them locked onto my head. I did an entire day of gardening over the weekend and didn't have to reposition them a single time. Definitely recommend.These glasses not only look great but are very comfortable. The grips to the nasal bridge and ears do not dig in but definitely keep them in place for runs. I have not tried yet on the bike, but anticipate it will be the samegreat glasses for running and riding. I love the nose and ear grips. The lenses are amazing in the sun and shade. Very happy with these glasses. Only drawback is if you have a very small face they will be large on you! I have ran a couple winter races in these already and love them.I am a runner and ordered these to wear them in my long runs outside in the sun.In California sun, they do amazing job.They protect my eyes and stay in place intact all throughout my runs.Roka is a great brand that is worth the investment.I love the look and the comfort and they stay in place and the lens are the perfect shade as I am a truck driver so while driving no squintingWay lighter than I hoped. They stay put, are super light and look great. What more could you want?Really nice quality, at least they appear so so far. And look good.Well made and great fit.
