Adult Bike Helmets
One adult helmet, built to cover a commute in the week and a trail ride at the weekend: 24 vents arranged brow to crown, a polycarbonate shell bonded to a multi-density EPS liner, and a visor you can take off in about five seconds.
What it is built around
- Ventilation that works at low speed
- Intake ports at the brow, a channel over the crown and exhaust at the rear. Stop-start city riding generates almost no airflow of its own, so the channel is what keeps it livable at a red light.
- A visor you can actually remove
- It clips to the front rim without tools. Leave it on for low evening sun and light rain, take it off for trail riding where an unobstructed view matters more.
- 9.77 oz, not the lightest on purpose
- The weight is in the liner, where it does the work. A helmet that is light because the liner is thin stops being comfortable the moment the road turns upward.
Sizing
Measure about one inch above the eyebrows with the tape level. If you measure exactly 22.8 inches both sizes work — take the M for a closer fit, the L if you plan to ride with a thin cap in winter.
| Size | Head circumference | Typical fit |
|---|---|---|
| M | 21.2''-22.8'' | Most adult riders |
| L | 22.8''-24.4'' | Larger heads, or riding with a thin cap |
Fit check in ten seconds
Tighten the dial until the shell sits level, then rock the helmet forward and back by the front rim. The skin on your forehead should move with it. If the helmet slides and your skin does not, it is still too loose and will not stay put in a fall.
