This is Giro's Manifest Spherical MIPS Helmet. Safety and protection from an impact is everything. Plenty of performance helmets have MIPS Brain Protection System (BPS), but Giro's Manifest has an improved, redesigned MIPS protection system. MIPS BPS has always been implemented directly against the riders head with a plastic slip-plane inside the helmet, but with Giro's Spherical MIPS technology, MIPS is combined with a ball-and-socket design to better redirect impact forces.

I ordered this helmet and its not the latest version of this model. If you are looking for that you need to go elsewhere. The description was misleading in my opinion. But I did manage to get the newest version of this helmet and can safely say its. fantastic helmet.

Giro Manifest Spherical MIPS Helmet (Matte Olive) (S)
Fits better than any helmet I have ever had. Feels very secure and I love the visor for early morning rides to beat the heat.

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)
XS47 - 51cm
S51 - 55cm
M55 - 59cm
L59 - 63cm
XL61 - 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.
