Trochę to trwało, ale w końcu GIRO przysłało mi następującą informację:
“We do recommend replacing your helmet every 3-5 years. Just from normal wear and tare the helmet can actual break down from sweat”.

Kolejna, bardzo ciekawa, informacja od GIRO:
[i][b]"Giro makes a general recommendation to replace a bicycle helmet every 3 years from date of purchase. This assumes the always vague “under normal use” set of conditions (which I will explain in more detail below). We emphasize that helmets should be inspected regularly for signs of damage or wear that might warrant replacement, and a helmet should be replaced after any significant impact, even if there is no physical evidence that the helmet was damaged. Customers can always contact us for questions about their helmets, too.
Every helmet owner treats his/her helmet differently, which is why we can only make a general recommendation. Some people might store a helmet on the top shelf of a closet where it falls to the floor every time they open the door, while other customers might keep it in a protective case. Some might leave it in direct sunlight or in a cabinet with solvents that can cause damage, while others leave it under the bed. Some customers ride and sweat 10,000 miles a year in their helmets while others might not get around the block. It soon becomes clear that there are far too many variables that can affect a helmet’s performance to make exact recommendations about the useable lifespan, which is why we prefer to be on the conservative side with our recommendation. The fact is we know that our helmets will go well beyond 3 years under many circumstances without a significant drop in performance".[/b][/i]
