i have carbon one. all my other helmets are made by hjc (carbon also).
uvex fits better than hjc. offcourse it depends your own head but to me it is better. especially cheek / cheekbone area.
and yes its light alltought hjcs are light but uvex is lighter.
i have used it mainly in road use alltought it is not real road helmet.
