Features
- AIS- Adaptive Impact System
- RHEON Impact Energy Cells which maximize absorption of low speed linear and rotational impacts, reducing forces transmitted to the brain
- 12K carbon fiber shell - Produces an extremely lightweight shell with superior penetration resistance
- Triple Density EPS provides a more progressive response to impact forces
- Expanded volume EPS - Strategic areas of the helmet have more impact absorbing EPS, more suspension between your head and the ground
- True Functional Ventilation (TFV) - When in motion air is forced through multiple air intake vents, then passed through aligned vent channels in the EPS and exits out multiple rear exhaust vents
- Quick Release cheek pads aid in emergency helmet removal
- CoolMax® removable washable and replaceable comfort lining system To help keep your helmet clean and feeling fresh
- 2 shells with 4 specific EPS for a perfect fit throughout the size range

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).
