Frequently Asked Questions
How do I fit a kids' helmet quickly with one hand?
Place the helmet level on the child’s head, hold it steady at the forehead with your free hand, and use your other hand to turn the dial until the shell sits snugly—no more than slight movement when you try to rock the helmet. Tuck the chin strap and adjust its length so only one or two fingers fit between the strap and the chin.
How tight should a child’s helmet be?
The helmet should be snug but not painful. It shouldn’t shift when the child nods or turns their head; test by gently rocking the helmet side-to-side and front-to-back. The front edge should sit about two finger-widths above the eyebrows to protect the forehead.
What if the dial or plastic parts feel flimsy?
Some users report mixed durability in internal adjustment parts. If the dial or plastic housing seems flimsy, stop using the helmet and contact the seller or manufacturer. Choose models with solid assembly, and consider replacing the helmet if any adjustment parts fail—do not attempt DIY repairs that could compromise protection.
