Built quality, age, and impact force all affect your helmet's ability to do its job. Check these essential points to test your helmet:
Check helmet's birthday - Replace it every 3-5 years even if it has not been in an accident.
Carefully inspect the outer shell for tiny cracks or deep scratches.
Inspect inner liner and EPS foam for any damage.
Check chin strap.
Check if the visor has severe scratches or cracks.
