Bell knows that, realistically, the vast majority of dirt jump and skatepark riders don't replace their helmets after falls. These new helmets are intended to address that concern, and can withstand multiple (approximately 3) impacts to the same location thanks to the EPP liner.
The liner is divided into seven segments which allows it to conform to anyone's head shape.
The Full Flex, above, goes for $100.
The Reflex is a more compact version of the Fullflex with similar features, but retails for just $65.
