How to Choose a Helmet

When looking to buy a helmet, first look for a "CPSC" sticker. This is an indication that the helmet has passed all required testing standards in the U.S.A. and assures you of the helmet's safety. It is suggested you buy a brand and size that fits well prior to making any adjustments. Once you find the helmet that fits well, you can make adjustments to the helmet to establish a snug fit. A comfortable and snug fit is paramount in choosing a helmet. It is not recommended that you purchase a helmet that you or your child can 'grow into.' A helmet that is loose will not provide the required protection, as it will not remain in place when impacted. This is the reason that we highly recommend you purchase a helmet that fits at the time of purchase

How to Fit a Helmet

The Fit
It is important that your helmet fit comfortably and snugly on your head. The helmet should sit level on your head, and the fit should be firm enough to keep the helmet from moving due to either vibration or impact.

Methods of Fitting the Helmet
Fitting the Foam Pads: Your helmet comes with pads installed at purchase. Some helmets also have extra pads to adjust the fit of the helmet. If your helmet has extra pads and the factory installed pads do not provide a snug comfortable fit, remove the pads from the Velcro™ inside the helmet and insert a different size pad or pads. Feel free to mix and match thicknesses so that the pads conform to your head's shape.

Adjusting a Rear-Fit System: Your helmet may also have a rear fit system which holds the helmet against the lower rear of your head. These systems have an adjustment mechanism. The two most popular mechanisms are a pinch-fit and a dial tensioner. The rear-fit should be adjusted so that it fits snugly against the back of your head.

Fitting the Fit-Ring: Many helmets come with a fit-ring which encircles the head. The fit-ring has an adjustment mechanism typically found at the rear of the ring. The ring should be tightened to a point that the fit is snug, yet comfortable.

Adjusting the Straps
With the helmet level on your head, fasten all straps securely so the straps provide equal tension. The Bicycle Coalition of Maine developed an 'Eye-Ear-Mouth Test' to check the adjustment of the straps. First look up, the front edge of the helmet should be barely visible. Second, the side straps should meet in a 'Y' just below your ear. Third, the chin straps should be snug under your chin, so that when you open our mouth wide, you can feel the helmet pull down a bit. If the straps do not meet these three criteria, adjust the straps beginning at the rear. First, adjust the straps through the rear fit system or rear fit piece. Next, adjust the 'Y' under your ear. You may need to loosen the side glides and lengthen either the front or rear strap. Be sure to retighten the side glides, when a good fit is achieved. Finally, adjust the buckle under your chin. Recheck the fit with the 'Eye-Ear-Mouth Test.'

The Right Fit

The helmet should be worn level on the head with the front approximately one inch or on finger's width above your eyebrow. The retention straps and helmet should fit as snug as possible. Check the fit of your helmet:


You may need to work with your helmet's fit for several minutes to achieve a proper fit. If a proper fit cannot be achieved, do not wear the helmet. Each helmet has a slightly different shape and fit. Find the one that fits you best. All adjustments should be checked each time the helmet is worn, making sure the fit is snug at all times.
