Frequently Asked Questions
How should I measure my child's head for the right helmet size?
Use a soft tape measure to circle the head just above the eyebrows and ears where the helmet will sit. Match that measurement to the helmet’s size range and use the included fit regulator and pads to fine-tune. If between sizes, choose the larger size only if the helmet offers thicker padding or an adjustable fit system.
Do vents really make a noticeable difference on hot days?
Yes. Vents that are well-placed and paired with internal channels or breathable mesh liners help move air across the scalp, reducing sweat and heat buildup. Removable, moisture-wicking pads further improve comfort and make it easier to clean away sweat odors.
How often should a kids' helmet be replaced?
Replace the helmet immediately after any significant impact, even if damage isn’t obvious. For normal wear, many manufacturers advise replacing helmets every few years because materials like EPS foam can degrade over time; check the brand’s guidance and watch for cracking, crushed foam or stretched straps.
