Sizing Chart

Giro Sizing Chart

Giro helmets come in lots of sizes, so chances are there's one that's going to fit you. A helmet that fits correctly should feel snug, with just a little room between your head and the sweat absorbent headband and pads.

Once you have a helmet that's the right size and has been properly adjusted you can customize the fit with the adhesive-backed sizing pads. Stick them to the helmet shell so that when you put the helmet on, it feels snug but not too tight.

You've no doubt noticed the straps hanging off your helmet. As pretty as they are, they're not there for decoration. If your straps aren't adjusted right, your helmet won't stay on properly. So pay attention. The first step is to make sure the helmet is on your head correctly. That means the front should be level with the back. If the front is too low, you won't be able to see hazards like wayward puppies and cliff edges. If the front is too high, you may look awfully rakish, but your helmet will not protect the front part of your head in a wreck. Once you've got your helmet on right, what keeps it there? No, it's not 'gravity' you smart aleck. The correct answer is, of course, the straps, which have been threaded through the helmet kind of like a shoelace. And just like a shoelace, before you adjust the fit, you want the two sides to be even. If your straps aren't even, tug on whichever of the rear straps is shorter until they are.

Next you'll need to check the position of the Tri Loc strap guides. You want both the front and rear straps to be snug when your helmet sits level on your head with the Tri Loc strap guides positioned just below your ears. To adjust the length of the straps open the Tri Loc and slide whichever strap needs adjustment up or down until it is in the correct position. Any slack in the strap must be pulled through the chin buckle. Now snap the Tri Loc closed and adjust the other side. The loose ends of the straps must be passed through the rubber "O" ring.

Close the chin buckle and tighten the combined straps until your helmet fits snugly. How snugly? You should be able to open your mouth, but only enough to take in carbohydrates. Here's a good test to see if your straps are adjusted right. Try and pull the helmet off from both the front and back. This is important. Grab the helmet with both hands and pull hard. If it can be tipped forward, you need to tighten the back straps. If it can be tipped backward, you need to tighten the front straps. If you want your helmet to stay on in an accident, you need to make sure it won't come off in your living room. If you cannot adjust the helmet so it cannot be removed with the straps fastened or so it does not move excessively, DO NOT USE THE HELMET. Replace it with a different size or a different model.

HOW TO [sel-ect ]A SIZE

A helmet that fits well offers the best protection and the most comfort. That's why Giro has invested so much in the art and science of helmet fit. Our proprietary sizing system was created using data collected by the International Standards Organization (ISO) on head shapes and sizes of the worldwide population. Most Giro adult helmets are available in 3 unique shell sizes (XXS/XS, S/M and L/XL). Our children's and youth helmets are available in 2 shell sizes (XS/S and M/L).

Follow these directions to determine which size is right for you:

1. Wrap a tape measure around your head just above your ears.
2. Compare this measurement (in inches or centimeters) to the sizing chart for the model you have selected.
3. Follow all fit and adjustment instructions in the Giro Owner's Manual.

If you can't adjust the helmet to meet these requirements, exchange it for a different size or model.

GIRO: FIT FOR WOMEN

Fit has always been a hallmark feature of Giro helmets. And our helmets have always been designed to fit both Men and Women. Why do Giro helmets fit better? The difference is in the head-form. Our helmets are built on proprietary head-forms using data collected by the International Standards Organization (ISO) on head shapes and sizes of the worldwide population. ISO data showed that unlike feet, there is no consistent difference between the head shapes of men and women. The only consistent difference is one of size: women's heads are generally smaller than men's. For this reason, all of Giro's adult helmets are offered in 3 unique shell sizes (most of our competitors only offer 2). By building our helmets in more shell sizes, we fit smaller heads more comfortably and precisely.

Our Roc Loc 2 and Roc Loc 3 fit systems are ponytail compatible for long hairs of either gender.
