snaplok This is the helmet that I got from the rentals dept. Ended up buying it for $20 after I took a really bad spill and cracked my head against the ground so hard I thought I broke the helmet. But not a scratch on it and the foam inside is fine too.



One of those, if it ain't broke don't fix it( hopefully..) )

Most helmets use EPS (cheap) foam. There are some that use EPP. Bern uses proprietary Brock foam (a type of EPP - they also have EPS models). Another foam type is Zorbium, but it is very rare (there is a hockey helmet with Zorbium - but Zorbium is warm and heavy).

EPS is ONE impact. If the foam is crushed, it's useless.
EPP and Brock and Zorbium are MULTIPLE impact. As long as the outer shell is intact, you should be good to go.

(most hockey and football helmets use vinyl nitrate padding)
the higher end hockey helmets use EPP now.

twin89 i think it is jsut one good impact and it is done. but i wouldn't go so far as to say that dropping it in the parking lot would finish it.

Enigmatic Gotta use your best judgement

if its a hard fall, it would probably behoove you to get a new helm.


Think about it, its kinda like an airbag in a car thats always deployed, but once you push it down, less air is in the bag, its closer to the steering wheel, therefore it no longer absorbs impact because the original impact-distance has become smaller.

Sometimes the fall doesn't crack the foam on the outside but instead on the inside (where you can't see it)so the absorption distance is shortened and your dome has less distance to travel, meaning your closer to the bad hard stuff.

The only way to REALLY know if your helmet is still good is to put on your surgery gloves, grab the scapal and disect your helmet and examine the layers....lol in which case it would be rendered useless and you'd have to get a new one anyway



On the flipside, I kinda think even a deffective helmet is better than nothing

unless your helmet is listed as "multiple impact", it is good for ONE impact and ONE impact only.
yeah, you need to look at the exact helmet that you have and make sure. i play many sports and ride motorcycles and it all depends on the type of material inside the helmet. my hockey helmets differ between materials and that will determine whether or not you need to replace it or not. as for motorcycle helmets, you're going to want to replace that on any drop. it seems like snow helmets can take some more abuse without structurally being affected, but in the end it is still your head. how much do you want to risk?
