Q: How do I make sure my bike helmet fits properly?

To work properly, a bike helmet must fit right and be worn properly. In order to offer you the best value and fit possible, Giro makes helmets in many sizes, including:

Large = 59 – 63cm / 23.25 – 24.75in.
Medium = 55 – 59cm / 21.75 – 23.25in.
Small = 51 – 55cm / 20 – 21.75in.
Universal Fit Adult = 54 – 61cm / 21.25 – 24in.
Universal Fit Women = 50 – 57cm / 19.75 – 22.5in.
Universal Fit Youth = 50 – 57cm / 19.75 – 22.5in.
Toddler = 48 – 52cm / 18.75 – 20.5in.

Step1: (Sizing your helmet) – In order to determine the size you need, you can measure the circumference of your head. Simply wrap a measuring tape around your head, being sure to locate the tape just above your ears and keeping the tape level front to back. Once you’ve determined the proper size, you can check to make sure the helmet fits correctly. If the helmet you own now doesn’t fit on your head with just a little room between your head and the headband when the fit system is loose, you should replace it with one that does. You should always wear the helmet positioned low enough in the front to protect your forehead, but not so low that it hinders your vision. Once you’ve got a helmet that is the right size, and positioned it properly, you can adjust the fit as follows:

Step 2: (Adjusting the straps) – Open the Tri Loc™ adjusters on the straps. Put the helmet on and slide the straps through the adjusters until they are located comfortably under your ears, making sure there is no slack in any of the straps. Close and lock the Tri Loc adjusters. The front and rear straps should now join at a point slightly below your ears.

Step 3: (Adjusting the chinstraps and buckle) – Fasten the chinstrap buckle and tighten the straps until the helmet fits snugly. How snugly? You should be able to open your mouth wide enough to eat. Make sure the chinstrap is well back against the throat, NOT on the point of the chin. Straps worn on the point of the chin increase the chance of a helmet coming off in an accident. Make sure the loose ends of the strap pass through the rubber O-ring near the buckle. If it does not, the strap may slide loose and the helmet can come off accidentally. Always wear the helmet with the chinstrap buckle fastened and the strap pulled tight.

Step 4: (Adjusting the fit pads) – The helmet fits correctly when it is held firmly but comfortably in place by the interior fit pads and the fit system (Roc Loc® or Acu Loc™). The fit pads inside the helmet are held in place by hook and loop fasteners. You can use any combination of the different thickness pads provided with the helmet until the helmet fits firmly and comfortably on your head.

Step 5: (Adjusting the tension of the fit and stabilizing system) – Your helmet may come with either of Giro’s patented Roc Loc® or Acu Loc™ fit and stabilizing systems. These systems attach to the helmet liner with either hook and loop fasteners or by snap-fit anchors. The systems are fully adjustable and they enhance the fit and stability of your helmet, but they are not a replacement for your helmets straps.
To adjust the fit and stability system while the helmet is on your head, push the buttons on the back toward each other to tighten the fit, and away from each other to loosen the fit. You can adjust the fit even more on systems that use hook and loop fasteners (Roc Loc Mini, Roc Loc 2 or older Roc Loc 3 models) by removing the helmet from your head, detaching the headband from the hook and loop fasteners, then moving the headband towards the front of the helmet to tighten the fit, or toward the back of the helmet to loosen the fit. On systems that use the snap-fit anchors (newer Roc Loc 3 models), you can adjust the fit by removing the helmet from your head, unsnapping the headband from the liner and moving the arms forward to tighten the fit or backward to loosen the fit. Roc Loc 4 and Acu Loc equipped helmets do not offer this adjustment. For safety reasons, we recommend that you do not attempt to adjust the systems while you are riding.

Step 6: (Adjusting the height of the fit and stabilizing system) – In addition to tension adjustment, Roc Loc 3 and Roc Loc 4 systems allow you to adjust the height of the system for optimum comfort. To adjust the height, remove the helmet from your head and then slide the Roc Loc arms up or down. Experiment until you get a fit that is most comfortable.

Step 7:(Checking the fit) – Once you think the proper fit has been achieved, grab the helmet with both hands and twist it to the left and to the right. If the helmet fits properly, the skin on the forehead will move as the helmet moves. If it does not, the helmet is too loose. Also, grab the helmet with both hands and try to remove it by rolling the helmet forward and backward as far as you can. Make a serious effort. THIS IS IMPORTANT. If you can roll it off the head completely in either direction, roll it forward so far that it blocks vision, or backward far enough to expose the forehead, it doesn’t fit correctly. If you cannot adjust the helmet to fit properly according to these instructions, DO NOT USE THIS HELMET. Replace it with a different size or model. Once you are satisfied that the helmet fits correctly and that all straps are properly adjusted and tightened, take a short test ride. Pay attention to overall comfort and helmet stability while riding. Make any minor adjustments to the fit pads, straps and stability systems to improve comfort or stability.

Q: What if I’m not sure if my helmet has been damaged?

If at any time you are unsure or have questions about your Giro helmet’s condition, you can send it to Giro for a free inspection. Our technician will thoroughly inspect your helmet, note any damage found and make our recommendations on whether the helmet should continue to be used. Call us at (800) 456-2355 or e-mail us at giro-consumersupport@giro.com for more details on this free service.

Q: What kind of warranty does my helmet come with?

Any Giro helmet determined by Giro to be defective in materials or workmanship within one (1) year from the date of original purchase will be repaired or replaced, at Giro’s option, free of charge when received at the factory freight prepaid, together with proof of purchase. If you have questions regarding the warranty coverage on your helmet, call us at (800) 456-2355, e-mail us at giro-consumersupport@giro.com, or refer to your helmet owner’s manual.

Q: How can I obtain replacement parts for my helmet?

Call us at (800) 456-2355 or e-mail us at giro-consumersupport@giro.com concerning replacement parts or any questions you may have concerning Giro products.

Q: Can I paint my helmet?

Giro does not recommend paints or solvents of any kind be used on the helmets. They can damage a helmet so that its protective capabilities are significantly reduced.

Q: How often should a helmet be replaced?

Giro has a general recommendation of replacing your helmet every three (3) years. If you are unsure of the condition of your helmet, or whether it should be replaced, call us at (800) 456-2355 or e-mail us at giro-consumersupport@giro.com for information on a free inspection.

Q: What do I do if my helmet becomes damaged?

Helmets don’t last forever. If the helmet is visibly damaged (cracked outer shell, crushed or cracked foam liner or any other damage) don’t use it. Some or all of the helmet’s protective capacity is used up when impacted, and the damage to a helmet is not always visible. If you have any questions about your helmet call (800) 456-2355 or e-mail us at giro-consumersupport@giro.com.

Q: How do I store my helmet?

After each use, allow the helmet to air dry and then store it in a cool, dry place where it won’t get damaged.

Note that excessive heat can damage your helmet. For example, in direct sunlight a dark gear bag, the interior of a car, or an automobile trunk can get hot enough to cause heat damage (damaged helmets will appear to have uneven or bubbly surfaces). Therefore, when not being used for a period of time we recommend that the helmet be placed back into its box or case and stored in a cool, dry place.

If you have any questions as to the condition of your helmet please call (800 456-2355 or e-mail us at giro-consumersupport@giro.com for information on a free inspection.

Q: How do I take care of my helmet?

Cleaning Your Helmet
Helmets are made of materials that can be damaged by many commonly available cleaners. Petroleum based solvents or cleaners are especially dangerous. They can damage a helmet so that its protective capabilities are significantly reduced. Many times this damage is not visible. For best results, clean the helmet using a soft cloth or sponge, warm water and mild soap (such as a mild dish soap).

Lice Removal
Yes, we said Lice! We get inquiries from day care centers or from people who share their helmets, and are concerned about lice infestation. Here’s a simple, effective way to get rid of them:

Step 1 – Do not use a spray of any type.
Step 2 – Place the helmet into an airtight plastic bag for 48 hours. Then, remove the pads and use a soft cloth or sponge, warm water and mild soap to clean the surface.
Step 3 – Discard the pads and plastic bag (keep bag out of reach of children due to suffocation hazard) and visit your local Giro dealer for replacement pads. Or, call us at (800) 456-2355 or e-mail us at giro-consumersupport@giro.com for replacement pads.
