The prepared cyclist in you knows to get these ahead of time for that day in the distant future when your helmet pads are either rotting or permanently odorized by your sweat. The frugal cyclist knows that the pads in the Aeon are made from X-Static material. This means they have anti-microbial/thermodynamic silver fibers woven in. They shouldn't get too stinky too quickly, yet when they do they're easy enough to remove and wash. You choose -- wash or replace. Any way you slice it, fresh helmet pads are nice; and they'll make your Giro Aeon feel like new again.
Even though the Giro Aeon comes with a set of replacement pads, having an extra set handy is always beneficial. This Giro Aeon Replacement Pad Set comes with all four pads to get you outfitted for comfort.
