Giro Eclipse Spherical Road Helmet Description:

The Eclipse Spherical Road Helmet is both the fastest and coolest aero road helmet that has emerged from the Giro range. It is a highly sophisticated & stylish lid that incorporates a Spherical ball & socket design which allows the helmet's outer EPS foam liner to rotate around an inner foam liner during a crash to redirect impact forces away from the brain. While safety is the number one priority, comfort trails close behind, so, Giro incorporated their Wind Tunnel venting and Roc Loc fit system to ensure riders stay cool and comfortable all ride long.


  • Spherical technology ball & socket design helps to redirect impact forces away from the brain by allowing the outer shell to rotate around the inner shell
  • Transform Air streamlines airflow across the helmet and reduce drag in multiple wind angles
  • Wind Tunnel venting system pairs up intake and exhaust vents for a constant rotation of airflow 
  • Progressive layering Dual-EPS foam liner protects from high and low energy impacts
  • Deep internal channeling directs the airflow though the helmet for a comfortable fit
  • Roc Loc 5 Air fit system allows users to easily fine tune the helmet fitment
  • Ionic + padding provides permanent odor protection

  • Ventilation: 17 Vents
  • Safety Features: Spherical MIPS
  • Color: Blue
  • Weight: 258g (Size S), 269g (Size M), 310g (Size L)

Helmet Measurements:

  • Wrap a measuring tape around your head
  • Make sure that tape is level from front to back
  • Note measurement and reference Size Chart
Circumference (cm)
S52 - 55.5cm
M55.5 - 59cm
L59 - 62.5cm
XL62.5 - 65cm

Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you've got the right size, you can adjust the fit.

How to Adjust Fit:

  1. Adjust the fit system at the rear of the helmet for a snug, secure fit. Some helmets also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.
  2. Adjust the straps so that they sit just below the earlobes.
  3. Adjust the buckle so that it rests against the back of the jaw/throat.
  4. Adjust the interior pads if needed.
  5. Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.

Note: All measurements are provided by the manufacturer and may vary depending on how measurements are acquired.
