The Giro Aether Spherical helmet rises with an elegant silhouette and is a true testament to performance innovation. Inside the Aether Spherical a dual-density EPS foam liner helps to manage a wide array of impact energies while also incorporating deep internal channels for adequate airflow. The proprietary spherical technology is integrated between the layers of EPS foam, giving the riders the benefits of MIPS Technology without and obstruction to comfort or cooling power. 

Features: 

  • Spherical technology's ball-and-socket design incorporates MIPS protection to redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash
  • Integrated MIPS technology brings rotational impact protection while enhancing fit and comfort
  • Structural integrity is bolstered by the shatter-resistant and translucent AURA reinforcing arch that runs though the helmet
  • Progressive layering brings a dual-density liner design to address high and low speed impacts
  • Deep internal channeling forces air to flow over the scalp, keeping you cool
  • Integrated rubber grippers on the front vents to hold your eyewear in place 
  • Roc Loc 5 air fit system is designed to enhance cooling, as well as fit and comfort

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.
