Designed for riders who do more than roll down a smooth trail, Fox Racing's Flux Women's Helmet provides solid coverage, without causing overheating. To do this, an EPS liner and ABS shell are carefully molded together for structural integrity, which allows the Flux to pass CPSC safety standards. The Flux helmet is cut low in the back for added protection, providing about as much coverage as you can get short of buying a full face helmet. The removable visor helps keep the sun and branches out of your eyes, and Fox's Detox retention system allows you to dial in the fit. Fox molded 20 large vent holes in the shell, so you'll get plenty of airflow on hot days. The vents are designed to force air into the helmet so it flows around and cools your head. An adjustable chin strap keeps everything snug while you ride.
