I had used several  Oakley Half Jacket for Mountain biking and broke my favorite glasses during a crash recently. Love the Half Jacket because of the weight but it get fog up during uphill mountain biking especially when you perspire. I want to get replacement glasses that is light, cover wide angle of my vision and does not fog up. I bought the Radar range which was designed for Golf and surprised that it works very well for Mountain Biking. It is very light, very bright for the iradium lenses and importantly it does not fog. I normally have to keep my glasses in the back pocket when I climb uphill but now, I just leave it on. It is much bigger than the half jacket but it came with the hard case. How often do you get case for glasses which is less than $100? Oakley is selling same glasses at $180 and this is a great deal with the case and extra nose piece. Highly recommended but I wish they sell different color lenses.
