The Oakley DRT5 has an integrated "Eyewear Landing Zone" that secures your glasses on the helmet. Oakley claims to be able to use this system while riding, but I personally would only ever use it if I were standing around, say fixing a flat. While riding 1. I would actually wear my eye protection. 2. I would be worried to break my (Expensive REAL Oakley prescription shades) in a crash and/or tree branches! Speaking of glasses, another reason that I chose the Oakley DRT5 is the fit of the glasses. There is more room and a more comfortable fit on this helmet compared to the Fox Speedframe & Speedframe Pro Helmets, especially the newer Speedframe Pro, which presses on the sides of your glasses, and even though "on paper" the Fox helmets, are a little less than the Oakley, they are front-end heavy, and press down on, or at least tap against, the top of the glasses pressing them against the bridge of your nose. The DRT5 never does this. The DRT5 just stays put on your head. Leave it to a company whos main product is eyewear, to get that aspect correct.
