鄙视CHI

[majy1208]

什么加拿大头盔协会还是联盟，卖学生头盔。等了一个多月不说，今天拿回来一看，2010年8月生产的，certified也是2010年。鄙视他们，生产出来3年都没卖出去。

自行车的头盔可能是五年吧 工地上的可能3年吧

Many of us believe that bike helmets have a limited lifespan before they become unsafe to use. This myth was put forth by the helmet companies themselves as a way to sell more helmets. As long as a helmet has not been involved in a crash, there is no reason to replace it. Sweat and sunlight have NO affect on a helmet. If the pads are worn out, they should be replaced, but the helmet itself should be good for as long as you own it.

化工合成材料可能会老化，有效期还是应该有的，至于多长就不知道了。
