I recently bought my husband a new Giro helmet from Performance Cycling here in Boulder. We have been cycling for a few years now and have started to accumulate old cycling helmets, most of which are Giro helmets. I emailed the company twice to find out what I can do with these used helmets and got no reply. I know that there probably isn’t a lot you can do with used helmets but it seems like a bit of waste not to be able to do anything with them. I do think that the Giro should have some suggestions on what to do with their products once they have been replaced.
In the meantime, I will keep them in the garage until I come up with a better idea than simply tossing them into the bin. I am now going to send Giro a link to this posting and see if I get any sort of response.
