I have been road cycling with these for the past few weeks. I am completely satisfied with the glasses at the discounted sale price. They fit a medium sized face perfectly and stay securely on throughout my rides. Though not tested, I'd be confident using these off-road as well. I found the rose+ lens to be perfect for morning rides. Dark enough when the sun comes out, but fantastic for morning light and tree shadows. I don't have to worry when riding through a tunnel. I wouldn't ride with Rose+ on a sunny midday ride, but they are excellent for just about everything else. No fogging issues to date.
