Fox Dropframe Helmet Maximum coverage for maximum fun More challenging trail riding demands more advanced protection. The Fox Dropframe Helmet provides more head coverage and protection than a standard trail helmet, with a deep coverage design that better covers the back of the head and ears, without the stuffy feel of a full-face helmet. This highly-ventilated helmet boasts MIPS(R) technology to reduce rotational forces on the brain, while a dual-density EPS foam helps to mitigate impact forces and offer increased protection. 8 big-bore vents with 7 exhaust vents direct a massive amount of air through the helmet, with a removable anti-microbial liner to keep the helmet fresh ride after ride.
