Bell Sports Segment Helmet The skate-style look never really gets old. But that rigid bowl-style shell feel can be a drag. That’s where Segment stands out. It has the classic shape of an old-school skate helmet, but its inspired design gives it head-hugging flexibility. So it’s much more comfortable. How is it done? A series of interior EPS foam segments are linked by a reinforcing skeleton, so it fits more like a comfortable cap than a helmet and still meets bike and skate safety standards.
