Excerpt from Snell Foundation

Why should you replace your helmet every five years?

The five-year replacement recommendation is based on a consensus by both helmet manufacturers and the Snell Foundation. Glues, resins and other materials used in helmet production can affect liner materials. Hair oils, body fluids and cosmetics, as well as normal “wear and tear” all contribute to helmet degradation. Petroleum based products present in cleaners, paints, fuels and other commonly encountered materials may also degrade materials used in many helmets possibly degrading performance. Additionally, experience indicates there will be a noticeable improvement in the protective characteristic of helmets over a five-year period due to advances in materials, designs, production methods and the standards. Thus, the recommendation for five-year helmet replacement is a judgment call stemming from a prudent safety philosophy.

 

Motorcycle helmet is a typical example of modern technology that based on obsolete, resource waste principals. 

Why don’t the engineers create good quality helmets that can be used for life-time? It’s possible. Changing only damaged parts, selecting right materials that do not deform nor degrade for many years exist.

Just imagine how much materials being wasted in world wide when riders replace helmet every five years? I have two Snell certified helmets: 2003 Suomy Gunwind, 2007 KBC VR-2 Gunslinger.  The condition of two helmets are decent, never been crashed on hard object in accidents. They all have minor scratches. The transparency of shield, especially Suomy Gunwind degraded noticeably. It developed tiny bubble all over the surface. I thought it would be fine for riding but yesterday’s short tour proved me I was wrong.  I could see things clearly but the foggy scenery irritated me.

I’m afraid I would find a shield for this helmet in the market. 

Manufacturers must look into environmental impact, longevity of their consumer products nowadays. It’s irresponsible, absurd business practice keep carrying on obsolete based principle.
