Re: [St] Score! and helmet life

[brettwilson21@xxxxxxx]

The claims made by manufacturers have some validity to them as well as 
serving to save them from getting sued if you wear a ten year old 
helmet and  bang your head on something and it splits open.

At the end of the day, nothing lasts forever. Different climates have 
differing effects, so as an example, on my little island of Oz, we are 
well aware of the detrimental effects of our hot climate. Plastics are 
particularly susceptible to break down from the harsh sun. Fibreglass 
and composite helmets will also eventually breakdown. As a rule of 
thumb we say a plastic helmet is good for three years of everyday use, 
exotic materials five years.

I believe there have been studies done on this type thing. I'm sure the 
interweb would be able to dig something up for you.
