Grit.CX tests out the Lazer Z1 helmet and Aeroshell:
The Z1 is lightweight (243g on my scales) and I found it very comfortable. The straps are soft and are the right length. Strap adjustment is easy, and Lazer’s Advanced Rollsys System works well. By turning a thumb wheel the fit tightens all the way around your head, resulting in a more uniform feel.
What really sets Lazer helmets apart is the detachable Aeroshell; a clear shell is included with the Z1 at no extra cost. Fitting it is a pretty straightforward affair, with no additional fixings required.
