This is a jaw pad for the Riddell SpeedFlex helmet. The size is 1 inch, which is the same as the standard size that comes with the Flex. Unlike the standard Flex jaw pad, this one has a built-in pad, which eliminates pain caused by the cold in winter. I purchased this set in the US, including a black version, but I only use the black one, so I'm selling this one. Although it is new and unused, there is a stain-like mark on the top of the pad (likely from the manufacturing process). It is not visible when the pad is attached to the helmet.
