Get Down And Get Dirty

The life of a skate-style dirt helmet is a hard one. The Giro Quarter Helmet is durable and has a polyurethane bumper to handle the wear and tear that comes with riding trails or the skate park.

The essentials are here - an EPS liner for impact management, a tough outer shell, riveted webbing anchors and plush, sweat absorbent pads that are easy to swap for dialing in the fit. Another standout feature - the polyurethane coating helps to protect the EPS liner from daily wear and tear. Plus it's available in a bunch of great colors and three super fit sizes.

The Quarter is one of the lowest-profile and lightest EPS-lined helmets in the entire Giro line.


  • Polyurethane bumper coating helps protect EPS liner
  • Fit kit padding
  • Complies with the US CPSC safety standard for bicycle helmets
  • Weight: 450g (M)

    Great Helmet! Amazing customer service!

    Always, always consider buying at BikeTiresDirect first. That would be my first and foremost advice. Super great experience buying here.

    The Giro helmet I picked out first had to be returned and swapped for a bigger one. Team was awesome to swap it out in a jiffy. Helmet fits right, feels great, and price was unbeatable. Thanks!
