Fox Racing Dropframe Pro Helmet It's Got You Covered Offering exceptional protection and coverage not often found in the non-full-face helmet range, the Fox Racing Dropframe Pro leads the pack with superior back and side-of-the-head coverage while still maintaining a high level of breathability and comfort. Covering the middle ground between the Proframe and Speedframe in Fox's helmet lineup, the Dropframe offers much of the protection found with a full-face helmet in a much more breathable package. With a total of 15 large vents directing airflow over the head, the Dropframe doesn't skimp on keeping you cool. To top it all off, the class-leading protection offered by the Dropframe earned this helmet 5 stars from Virginia Tech's Bicycle Helmet Rating program, the highest rating ever given to an open-face helmet. Ride confidently with the Fox Dropframe Pro.
