This helmet is incredible. It is by far the lightest and most comfortable helmet I have ever had. My favorite helmet until now has been the GP-Tech by AGV. I own about 8 of them, but this carbon fiber is extremely light, unbelievablely sturdy, with excellent airflow. The air wing significantly reduces drag: translation: more time on the saddle. The amount of vents will help keep you cool on hot summer days, it was 93 today and I felt great in my helmet. You might say, "yeah, but $4200! Are you kidding me?!" My response, yep! Worth every penny, you have no idea. Everything else pales in comparison to it. My AGV's are almost a grand, not cheap. This RXV is 10 times better.
