Fox Dropframe Flow Mountain Bike Helmet
The Fox Dropframe Flow is a high-coverage, open-face mountain bike helmet built for enduro riders who want maximum protection without committing to a full-face. With extended coverage around the ears, jaw and back of the head, plus Mips and dual-density Varizorb EPS, it delivers one of the most secure fits available in a 3/4-style helmet. Increased ventilation, removable liners and a GoPro mount make it a practical choice for long trail days and technical riding.

Maximum Open-Face Coverage
The Dropframe Flow offers the most complete coverage Fox provides in an open-face helmet. Extra protection around the ears and jaw gives riders confidence on steep, rocky and unpredictable terrain.
Advanced Impact Protection
Mips helps reduce rotational forces during angled impacts, while Varizorb EPS spreads impact energy across a wider area for improved safety.
Ventilated for Long Rides
With 8 Big Bore intake vents and 7 exhaust vents, airflow is a core part of the design. The fixed visor helps channel air directly into the vents to keep you cool and comfortable.
Customisable Fit
The helmet includes multiple cheek pad and headliner thickness options, allowing riders to fine-tune fit and stability.
