Fox Speedframe 5050 Helmet
Product Details
The Fox Speedframe 5050 Helmet delivers essential open-face protection with performance-focused features for riders who demand comfort, control, and style on every trail. Combining Fox’s aggressive design DNA with advanced safety technology, this helmet is engineered to keep you protected while maintaining a lightweight, ventilated, and comfortable fit for all-day riding.
At the core of the helmet is the MIPS system, proven to reduce rotational forces by absorbing and redirecting energy during impacts. Channeled, in-molded EPS enhances airflow to keep your head cool during long rides, while the removable, washable moisture-wicking liner manages sweat and odor for lasting comfort.
Fit is fully customizable thanks to the 360° Fit System, which allows you to adjust both the circumference and the back cradle while wearing the helmet, ensuring a precise, secure fit on every ride. The one-hand adjustable visor is compatible with sunglasses and goggles, and a dedicated sunglass storage solution provides added convenience on the trail.
Developed by Fox Racing, the Speedframe 5050 Helmet combines safety, comfort, and iconic style, making it a shred-ready choice for aggressive mountain biking.
