I think as many have already offered, your health is the MOSt important piece of this puzzle. With that said, we are glad that you are not injured!!

Louis Garneau does indeed offer a crash replacement as others have mentioned. In fact, I have replaced helmets out of the shop for that very reason. The damaged helmets are generally used to pinpoint any issues or help their research teams in designing new helmets.

AS always, helmets do run a bit differently from brand to brand, so make sure that you find something that fits you.
