Features
- STANDARD
- ECE / DOT approved
- ADAPTIVE IMPACT SYSTEM
- Polycarbonate alloy shell construction produces an extremely lightweight shell with excellent penetration resistance
- Impact Energy Cells made of RHEON, the Impact Energy Cells maximize absorption of low speed linear and rotational impacts, reducing forces transmitted to the brain
- Multi-density Expanded Polystyrene (EPS) Technology provides a softer EPS. Critical zones have been fine tuned for a progressive response to low speed and high-speed impacts
- Expanded volume EPS means strategic areas of the helmet have more impact absorbing EPS, more suspension between your head and the ground
- Expanded Polystyrene (EPS) chin bar creates an additional element of impact mitigation, and is used in the chin bar for its superior damage resistance, and energy absorbing properties
- Clavicle shell relief zone creates a soft zone filled with EPS and EPP to aid in reducing clavicle injuries
- Custom molded rubber trim with integrated nose guard
- Lightweight custom visor screws and stainless steel D-rings
How to measure
Use a soft tape measure starting at your forehead about one inch above your eyebrows, wrapping across the largest portion of the back of your head. Match that measurement to the chart. No soft tape? Wrap a string the same way, then measure it flat with a ruler.

One official FLY chart covers all moto/MX and street helmets (the brand publishes separate MOTO and STREET chart images, but they are identical). Snow and bicycle helmets use their own charts. cm ranges are official; inch ranges converted from cm (FLY publishes a ruler-style chart, not an inch table).
