was at my local REI fitting helmets on my girl and the salesguy was telling me that helmets deteriorate on the shelf even after 5 years / compromised after first impact (even dropping it in the parking lot)
this is crazy to me, my helmet has taken some abuse, kissed a few trees. should i be concerned?
he also mentioned alot of companies will replace your helmet after impact... really?
Most helmets are crush helmets. One and done. There are models out there that are multi impact helmets. Regardless, after taking a violent blow, almost all types are done.
As with any type of gear, it does have a shelf life. Foams and like materials do break down over time. Foam being the primary source of protection that makes up a helmet. That's just the nature of things.
I don't know about companies replacing your helmet after an impact. Maybe some do. You'd have to contact them.
well im not made of money, so i dunno how i would replace after every impact.
You're going to be a drooling pile of poo if you've had that many impacts. Dropping your helmet is not going significantly reduce the effectiveness of your helmet. Unless you are slamming it to the ground. If you are cracking you noggin on the trees, terrain park, enough to make a "crush" zone than yeah you need to replace it. You also probably have a frequent flyer card at the medical clinic as you'll be probably knocked out by these impacts with a helmet on.
Minor blows, it's probably going to be fine. Also, like mentioned get a multi impact helmet if you are truly worried about the one and done models...
