yes I forgot about all the "evaporation" that the helmet suffered while in a plastic bag, in a helmet bag, in a sealed box, kept at 71 degrees in the dark for its entire life. I've inspected the EPS foam and it has all the characteristics of a brand new helmet, springy, no flaking, no dryness, etc. I have motocross + mtb helmets i've tossed after 3 years from them constantly being wet/dirty and having the EPS go hard/brittle.
But please continue to tell me how a budget lid, with the same shell size as the one 3 sizes up, is somehow safer than one of the best designed helmets you can buy with a few extra years on it. I'm sure HJC is using the exact same quality of EPS and materials as Arai as well.
As great as FortNine is, please show me the scientific study he highlights his numbers from. Manufacturers recommend anywhere from 3-7 years to cover their *****. I'd rather use my judgement and experience to decide when the helmet isn't good instead of the marketing guy + lawyers making some trivial number up.
check-out an actual peer reviewed study instead of some guy making fun youtube's:
