Quarter MIPS Helmet

Giro's lowest profile helmet is now available with more protection than ever for your most thrilling rides. Take the Quarter MIPS Helmet to the trails for affordable protection, without added bulk. MIPS, or Multi Directional Impact Protection System, refers to the Swedish technology that can be added to helmets in the form of a thin inner layer that rotates slightly upon impact to absorb the brain-damaging rotational energy created in certain crashes. Less rotation, less likelihood of a head injury.

As an extra, Giro made the decision to add a polyurethane coating around the outside of the EPS liner to give the foam some protection in the areas where it's most likely to be damaged during bumps and scrapes. The included Fit Kit foam pads are removable so you can get a customized fit, and they can even be washed, if you're so inclined. Eight vents keep the Quarter breathable, and rather than use their universal shell size, Giro makes the Quarter in three Super Fit sizes to make sure you're getting the right fit.

  • Protection for the trails is now lightweight and affordable
  • Three layers of impact-absorbing materials work towards safety
  • Removable Fit Kit pads help to get a customized fit
  • Venting keeps air moving overhead on warm rides
  • Giro makes "the gear that gets you there"
  • Ages 5 and older


    The helmet body broke apart where the strap connected after only third time using helmet. Absolute crap.

    Great helmet, great price!

    • Familiarity: I gave it as a gift but have feedback to share

    I gave this as a gift to my nephew, he is 9 years and his head is 21.5" in circumference, I went with the medium (21.75 - 23.25in) and it fits him well but has plenty of space to allow for growth in the next few years. The price is great for a helmet with MIPS! He loves the simple style and matte black color, much more 'mature' than his spider man helmet from when he learned how to ride a bike.
