As a parent, the safety of your child is top priority while they are out riding. A helmet can arguably be the most important piece of protective gear they will wear. Rocky Mountain ATV/MC provides a comprehensive selection of some of the best children’s helmets available on the market in light-weight, ergonomically advanced designs that offer the latest in safety technology and fresh new styles as well.
Each helmet we carry has a sizing chart in the description to help you find the best fit for your child. Although helmet sizing varies among manufacturers, there is a universal method of measuring your child’s head for the best possible fit: Measure the circumference of their head from 1” above the eyebrows and around the largest portion of the back of their head. This measurement should provide enough information to gauge which helmet size will be right for each style. Remember, you want the helmet to fit well – not too loose and not too tight – but snug for the best possible protection.
Extra room inside the helmet can reduce its protective power. A test you can perform to check for proper sizing is to see whether you can get the width of your finger to fit between the helmet padding and your child’s forehead. If you can, the helmet might be too large. To get a feel for a certain helmets’ sizing, checking out the customer reviews for the product can be useful. Sometimes the best reference for fit comes from someone who has tried it out first. If for any reason the helmet doesn’t fit, give us a call and take advantage of our Fit Guarantee - Apparel Exchange to get the correct size you need.
An additional protective item you might consider purchasing in conjunction with your child’s helmet is a quality neck brace. A child’s neck is much more fragile and can be subject to the weight of the helmet and the impact of the ride. Not only can a neck brace hold your child’s head steady as they ride, it also protects their neck from painful movements in the event of a crash. We have a great selection of neck braces that will offer the protection you want for your child as they ride.
We have one of the largest selections of Snell & ECE approved kids ATV helmets available on the market from trusted brands like 6D, Fly Racing, Fox Racing, HJC, One Industries, Thor and more. Take a look at the variety we carry today so that your kids can be protected on every ride they take.

Great fit and comfort. The ventilation is also very good on this helmet. Price was reduced after I purchased it and RMATV gave me a credit! Talk about great customer service.

Wanted to give information I wish I had available to me. This helmet is very comfortable. I'm coming from a Bell Moto 10 spherical, and Moto 9 MIPS. I would say the fitment is similar to those but better. I wear an XL in Bell, and ordered an XL in 6D. The three things I noticed were different for me were: 1. It was easier to drink from my water straw in the 6d while wearing. I'm not a racer, so I just fish the straw through the face opening. 2. the space 6d made for the coms in the ear area is awesome. I have medium to large ears and they weren't touched at all. The Bell would flatten my ear (not hurting or anything), but the 6d seems to have zero pressure on them. For that I would vote the 6d more comfortable. Lastly, it feels roomier to me on the chin bar than the Bell. I still love my Bell helmets, wish all companies had the magnetic cheek pads, but wanted to help people with info I was looking for. Also the ventilation is more like the moto 9 than the moto 10. FWIW Leatt helmets don't really fit my head, I get hot spots. Hope this can help someone who's thinking about getting a new helmet.

I have had a Bell 9 helmet since 2019 and it has been fantastic. Great fit, great quality, great longevity! The visor is flexible and doesn't die on the first fall and the screws are easy to adjust with your gloves on. The magnets on the cheek pads and the strap are so convenient that those selling points alone make this a great helmet for someone who races every weekend. I may just go back and order another one!
