Don't they use EPS for car bumpers too? Do they recommend car bumpers be replaced every 3 to 5 years?

Snell knows a lot about helmets and their views on this subject should not be dismissed lightly, even though we disagree with them...Deterioration depends on usage, care, and abuse...The standards do not permit manufacturers to make a helmet that degrades from sweat...Manufacturers put UV inhibitors in the plastic for their shells that control UV degradation. If your helmet is fading, maybe the UV inhibitors are failing... EPS is a long-lived material little affected by normal environmental factors
