Item # GIR007L

The quarter keeps you whole.

On the outside, the new Giro Quarter Helmet may look relatively similar to other low-profile, skate-style helmets out there, but it's actually a cutting-edge lid that makes a fine home for your dome.

The Quarter is Giro's entry-level helmet into the gravity-chasing, dirt-jumping, pavement-pounding arena of riding, aimed at riders who aren't riding at high cardio thresholds or for lengthy stretches of time. Rather, it's meant for big impacts. This tradeoff means it's not as heavily ventilated or as light as some cycling helmets, but the tradeoff is superb protection that's as thorough as you can get without putting on a full-face. Again, it's not as light as a road helmet, for example, but the Quarter is actually the lightest helmet Giro's ever made with an ABS (high impact) shell. The exterior is comprised of a polyurethane bumper that encases the EPS foam liner, altogether forming a triple shield of protection. Giro's Super Fit shape and Fit Kit replaceable pad system ensure that you can dial in the perfect feel for your Quarter.

  • A skate-styled helmet for hitting the pump track
  • Burly construction for big impacts at jump parks
  • EPS foam absorbs and dissipates energy from hits
  • ABS-shell is seriously tough for major impact
  • SuperFit replaceable pads let you dial in fit
  • Entry-level pricing won't break your bank
  • Ages 5 and older

Comfy commuter

I've used it several times

I got this for commuting around town and have been very pleased. Fits my head well and is very well priced. Nothing fancy here but that is exactly what I wanted. Comes in a number of cool colors and will for sure keep your dome safe. Let me know if you have any specific questions on this helmet.

Good commuter.

I've put it through the wringer

I picked this up to wear while commuting around town (and after my face met the asphalt during a slightly tipsy bike ride). It’s not the most aerodynamic helmet, and far from being the lightest on the market, but it protects my noggin comfortably and looks decent doing so. I got the matte whiskey color and it’s really cool looking!

Nice helmet

True to size

I go this helmet for use with my commuter bike. I wanted something that was more casual but still comfortable with plenty of vents. Overall I'm very happy with the purchase and would recommend it.
