2. Improved ventilation: Premium helmets incorporate efficient ventilation systems, and the full-face flip-up MAX is no exception. At highway speeds, you can actually feel the vents working. But, like some other helmets with large chin vents, don't be surprised if a bit of tiny debris sneaks past the opening and into your eyes. This became problematic when I discovered that the spring-loaded, drop-down internal sun shade only retracts when I push the release button atop the shell. Typically, these cool, jet-pilot-like sun shades slide up and out of the way if I press on the bottom of the shield. It's not a huge problem unless you have $#!! in your eye.
