A well-fitting helmet is crucial for optimal protection. When trying on a helmet, make sure it sits level on your head and covers your forehead without obstructing your vision. The helmet should feel snug but not too tight. Adjust the straps and retention system to achieve a secure and comfortable fit.

It’s essential to measure your head circumference and choose the appropriate helmet size to ensure a secure and comfortable fit while cycling. Always refer to the manufacturer’s sizing guidelines for the specific helmet brand you are considering.

Consider the helmet’s ventilation
