Study: Helmets do not degrade with age and use

[nuliajuk]

Some years ago I contacted Louis Garneau after replacing a helmet, to ask if I should just throw the old one away. I was surprised when they got back to me to say that the old L.G. helmet should be just fine and I didn't need to toss it even if it was 7 or 8 years old. I still have it as a backup, although it's not as good a fit as the Specialized helmets I replaced it with.
The first of the Specialized helmets did break up after about 5 years, but not in the foam section. Rather, it was the plastic holding the nylon straps to that helmet body that disintegrated. Built in obsolescence, I suppose.

That's fascinating!
