The Bell Arella is essentially a women’s version of the Muni urban helmet, scaled-down to fit a greater percentage of women’s heads, and styled-up to fit their sense of fashion. Despite its sophisticated sass, the Arella is full-featured and all business under the pretty paint: the OneStep Plus fit system, the integrated lights, the mounts for additional front and rear lights, the mirror mount, the ratcheting buckle—they’re all there, just like the Muni.
